Chjade84 convinced an Automated Laser Corporation 20 watt fiber laser to play "Still Alive," Jonathan Coulton's epic anthem for Valve's video-game Portal; as a lagniappe, the laser performs this feat while carving Valve's Aperture Science's logo into a stainless steel plate.
There has been a lot of interest in these stainless plates with the Aperture logo (thanks!). I've sent a few emails to Valve asking for their permission to make them for you - it is their logo after all. If you want to be kept in the loop send me a message and I will keep you informed (probably $20-$30 shipped -- stainless ain't cheap!). Thanks again!
