I was talking to an electrician on the weekend and he was telling me about a
"laser / level" that a friend of his had bought to layout tile. As he
explained, it sounded like one could hang the laser system on the wall and
then adjust the tile angle and size to project a grid onto the floor. I
tried to google it but only came up with laser squares. The more I think
about it I wonder if such a system could even exists? since the height and
location of laser would cause the laser image to "keystone" as it got
further away. THOUGHTS?
