Yep and eyup, i guess; I'm sure that there are larger prisms out there ( I had to use only what was laying around the house for this project, except for the blue diodes and the lenses.) Thanks Michelrietveld! Unfortunally that's not my garage, that's an upstairs bedroom (hobby-room) and it's a total disaster area. My wife wants me to clean it up. I always say "after this last project I will" but the projects seem to be ongoing and never-ending, so .. it never gets done ..
