		<description>The folks at &lt;a href=&quot;http://www.anchoroptics.com&quot;&gt;Anchor optics&lt;/a&gt; must have figured out that if you &lt;a href=&quot;http://www.anchoroptics.com/documents&quot;&gt;give away more than thirty pdfs of classic science project books involving optics&lt;/a&gt;, people who want to do the projects will know where to shop. My favorite: &lt;a href=&quot;http://www.anchoroptics.com/documents/download.cfm?id=41&quot;&gt;Fun With Fresnel Lenses&lt;/a&gt; (22.9 mb pdf).</description>

		<description>Hey! &quot;Anchor Optics&quot; is Edmund Scientific! 

 I have fond memories -  more of browsing the catalog than of the crappy junk itself - but still, for a geek in the dark days before the internet, this was pure pr0n.</description>

		<description>Also check out AnchorOptics for the tubes and focusing helicoids that may let you make that 50mm f/0.8 lens you&apos;ve been dreaming of for your SLR (if you&apos;re anything like me that is).</description>
