It’s a glass laser block! I used my green laser pointer on glass blocks in the lobby at building 100 at Daytona State College. This was a lot of fun and I enjoy effects like these. I used a six-second exposure and positioned my Canon Rebel XTi on a makeshift tripod and used the 10 sec. timer to avoid jostling it.
