Sorry, I didn't realise there was a difficulty threshold or that the project must only use lasers. I apologise for my complete incompetence.
I was more thinking of easy projects but it was something I looked into. I am thinking of doing a projectable music visualiser using the lasers, only then requiring up/down movement
GRL is often interesting to haver a look at for some cool projects. Reminds me - i must check up on their progress now!
