I hope that you enjoyed this little tutorial. Complete article can be found on my site but all the information needed to make one of these by yourself is listed here, in this Instructable article. Full article at Metku
Technique by itself is very simple but it involves several steps. It is best to try this out with smaller scrap pieces of acrylic first.
I just feel that combining multicolored engravings with bit of movement is just the ticket to impress your friends. Mount this to the car window, on top of the amplifier stack inside the trunk, side of a computer case, frame it to the wall etc. Tons of uses and you can personalize it the way you like. An animated heart to your loved one perhaps? ;)
As this was my first instructible, please, give comments and feedback. I'm also happy to answer questions about engraving and modding in general too.
