On one day notice, I set up a simple laser display for for my son's middle school PTA dance.
Used a 50mw Green Pointer and a 200mw Red like the one in my avatar.
Projected them thru two rotating first surface mirrors onto the white ceiling.
The pattern was about 30 feet across.
Some of the rotating pattern was blocked in photo.
Ran 1.5 hours continuously on two AAA and one #18650 batteries.
