			<content:encoded><![CDATA[<p>Kristina Larsen on her recent laser cutting adventures:</p>
<p><a href="http://www.flickr.com/photos/kristinalarsen/4003485790/" title="P1000373 by kristinaliv, on Flickr" onclick="javascript:urchinTracker ('/outbound/article/www.flickr.com');"><img src="http://farm4.static.flickr.com/3191/4003485790_f93e3e0687.jpg" width="300" height="234" alt="P1000373" /></a></p>
<p>Most of the time I&#8217;ve spent with the laser cutter has centered around learning what different materials will do when cut or etched, and thinking about how to use Illustrator as a pattern-cutting tool. I&#8217;m not sure that I made anything before this that I couldn&#8217;t have made some other way in a similar amount of time. But in making this felt box I finally took advantage of one of the best features of the tool &#8212; generating multiples!</p>
<p>I made a little pile of them in like 10 minutes. So exciting!</p>
<p>They&#8217;re cute and fuzzy, utilitarian, and fun to fold. I think they look happy when they&#8217;re full of stuff.</p>
<p>At first I tried to make a test version out of paper, but it didn&#8217;t work very well. (Paper&#8217;s not as pliable and forgiving as felt.) I also had been trying to do all the design thinking in Illustrator ahead of time at home, so I could simply go into the learning studio, cut out the thing and be done. But it didn&#8217;t really work out this way &#8212; some tweaking was required.</p>
<p><a href="http://www.flickr.com/photos/kristinalarsen/4002720669/" title="P1000363 by kristinaliv, on Flickr" onclick="javascript:urchinTracker ('/outbound/article/www.flickr.com');"><img src="http://farm3.static.flickr.com/2671/4002720669_8ffac5ec71_m.jpg" width="240" height="180" alt="P1000363" /></a></p>
<p>Turns out it&#8217;s much much easier to cut one out of felt, mess with it (cut it up, draw on it, squish it), adjust the Illustrator file, cut out a new one, and repeat as necessary. Hey, I guess that&#8217;s rapid prototyping in a nutshell.</p>
<p>Possible next steps are to try scaling them differently (shorter sides, more rectangular shapes, steeper angle to the top) and incorporating a second contrasting color showing through cut-outs. Since I only can visit the learning studio once in a while I still am doing a lot of thinking about the design away from the laser cutter. But I&#8217;ve also got four of them to futz with while I re-work the design.</p>

<p>The video shows a set of materials for light experimentation: A simple screen made with an embroidery hoop and a self-made moving LED light source. I wanted to create a set-up that can work on a table or be mounted on a wall,  something that can be changed to produce different light patterns. In this instance, the light is moving through a translucent tube, photos below show the same light source inside a  mirrored prism and other tunnels.</p>
<div style="float:left; margin-right:10px"><object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width="NaN" height="NaN" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0"><param name="flashvars" value="intl_lang=en-us&amp;photo_secret=c41824490f&amp;photo_id=3272673940&amp;flickr_show_info_box=true" /><param name="bgcolor" value="#000000" /><param name="allowFullScreen" value="true" /><param name="src" value="http://www.flickr.com/apps/video/stewart.swf?v=71377" /><embed type="application/x-shockwave-flash" width="NaN" height="NaN" src="http://www.flickr.com/apps/video/stewart.swf?v=71377" allowfullscreen="true" bgcolor="#000000" flashvars="intl_lang=en-us&amp;photo_secret=c41824490f&amp;photo_id=3272673940&amp;flickr_show_info_box=true"></embed></object></div>
<p>I got interested in the beautiful effect of a point light source moving through a mirrored tunnel when I worked on kaleidoscopes with artist John Edmark. In the last couple of months, I made this equipment for my own experiments and I would like to try it with our visitors on the museum floor. I think at  first I was excited about using this with a Mylar tube (left) , but recently I like to use mirrors and translucent materials.</p>
<p>Once I had started with the embroidery ring as a screen I decided to make everything out of wood.  The linkage I used to move the light back and forth worked pretty much right away.  It was harder than I thought to find a good light source and that led to inventing one specially for our needs.</p>
<div style="float:left; margin-right:10px"><a href="http://apps.exploratorium.edu/blogs/ls/files/2009/08/dsc_9166.jpg"title="Projection through a mirrored triangle " rel="lightbox[pics553]"  ><img class="attachment wp-att-585" src="http://apps.exploratorium.edu/blogs/ls/files/2009/08/dsc_9166.thumbnail.jpg" alt="Mirror Tunnel " width="191" height="175" /></a></div>

<p>We use a LED star with a simple circuit board.  It is much brighter than a Mac light, stays at the same brightness for a couple of hours on battery power and can also be plugged in using a 4.5V power supply. On top of being bright, the LED star stays cold and is small enough to fit nicely into the light tunnels I use.</p>
<p><a href="http://apps.exploratorium.edu/blogs/ls/files/2009/08/3256459538_c395902459_o.jpg"title="Projection through a plastic lid" rel="lightbox[pics553]"  ><img class="attachment wp-att-593 alignleft" title="light projected through a deformed plastic lid" src="http://apps.exploratorium.edu/blogs/ls/files/2009/08/3256459538_c395902459_o.thumbnail.jpg" alt="3256459538_c395902459_o" width="200" height="150" /></a>While playing with my new equipment, I noticed that some of the most stunning effects originate from bringing the light source really close to a reflective or translucent material, the light projection can work like a magnifying glass and show the detailed structure of the material projected on a surface.</p>

<p>In the last couple of weeks, I have spent many evenings playing around with our new laser cutter in the learning studio. So far I have not started any big projects, but just enjoyed the opportunity to work with such different materials on the same machine. It&#8217;s astonishing how the cutter can produce acrylic gears, colorful fabric designs, etchings in a mirror surface, fragile paper ornaments, or wood cut-outs (more in this <a href="http://www.flickr.com/photos/33666201@N04/sets/72157616669278964/" onclick="javascript:urchinTracker ('/outbound/article/www.flickr.com');">Sample Gallery</a>).</p>
<p>The image to the left shows quick 10 minute clip art designs we used to test materials, below is an example of a bigger project by Kristina Larsen. She just started  to use the laser cutter with Adobe Illustrator for her artwork.</p>
<p>&#8220;<em>I&#8217;ve been wanting to do something with this design for a long time. The black felt is made of polyester and the rest is a slightly thinner rayon/wool blend. The non-synthetic felt looks and feels much nicer, so I plan to swap out the black with the good stuff in dark brown. Once it&#8217;s all together I&#8217;ll attach it to a backing material, probably fabric.</p>
<p>I find the process of fitting the pieces together immensely satisfying, like working on a squishy jigsaw puzzle. I&#8217;m also happy with the combination of precision cuts and organic lines, and that I&#8217;ve managed to use computer and laser cutter to make something warm and handmade feeling.</em>&#8221;</p>
