Yep i just got in from maplin. I got an entertainment style laser because it was cheaper than buying a seperate laser part on it's own. It creates some nice effects via motorised mirrors and it is quite small. I will take it apart and try and mod it to produce adiquite effects for in case display or just extract the laser unit itself. Here is more info about the laser. http://www.miraclebeam.com/lightshow.asp Hopefully I can mod it to get some good effects inside my case, I will continue to investigate the prospect of simulating a visable beam inside the case. I found exposing the laser to a small ammont of smoke vapour resulted in a partially visable beam. I will get some action pics up after I get new batteries for my digi cam If anyone is wondering the laser device cost £40 from maplin.
