Hi, as many of you, I'd love to have some kind of laser projector to write messages or draw pictures.
But it's ether expensive or tricky to realise an XY laser show.
Anyway, it doesn't stop me from writing with a laser.
I just do it a different way!
My idea is to create a path for the laser, which illuminates letters or shapes.

Well done!
How good can you see it under normal roomlight? without camera multisecond exposure?
Maybe I wouldnt tell the people about your selfmade Laserglases XD altough I'd do something similar it isn't the most reliable and safe solution.

Actually, on normal room light condition, we can see ray quite well!
I had to take multisecond exposure because what we see is never the complete ray, but small flashes on dust.
I also had to sprinkle chalk dust to help the camera.
Remember your eyes are far more sensible than the camera! (especially with a 100mW laser ; ) )
