A simple set of tesselated M.C. Escher fish. Martin Raynsford (link below) provided the original fish DXF, but I have added a frame sized for 42 fish.Martin's suggestion is to stain some wood light and some dark and cut two different colors of fish for neat patterning.Here's a link to Martin's blog entry with the original design.http://msraynsford.blogspot.com/2012/03/escher-fish.htmlHere's a link to one of the photos on my Flickr; browsing around will reveal additional photos of the process I did not post here:http:[email protected]/* <![CDATA[ */!function(t,e,r,n,c,a,p){try{t=document.currentScript||function(){for(t=document.getElementsByTagName('script'),e=t.length;e--;)if(t[e].getAttribute('data-cfhash'))return t[e]}();if(t&&(c=t.previousSibling)){p=t.parentNode;if(a=c.getAttribute('data-cfemail')){for(e='',r='0x'+a.substr(0,2)|0,n=2;a.length-n;n+=2)e+='%'+('0'+('0x'+a.substr(n,2)^r).toString(16)).slice(-2);p.replaceChild(document.createTextNode(decodeURIComponent(e)),c)}p.removeChild(t)}}catch(u){}}()/* ]]> *//6893876136/in/photostreamAnd here's a video of the laser cutter cutting two fish, my favorite part is seeing the part drop when the cut is completed:http://www.youtube.com/watch?v=Qs1zGo-hFho"One Art Please!" - Zoidberg.Get some 1/4" plywood (or whatever material you like) - I used a sanded birch 2x2' sheet from Menards, cut it down the middle, then stained each half different shades, varnished, and then cut. I provided a file with the fish int he frame, because I know someone will ask for it. But I prefer to cut the fish separately, using Martin's layout, which preserves the wood grain for individual fish and gives a nice visual texture to the finished piece. If you are not using wood, then I suppose there's no reason to prefer it.Optionally, cut the frame parts, glue and clamp, and fill with fish!
