Laser Wall Art

Step 3 I took 3 different images, due to shorter exposures

You can be as elaborate as you want by taking many exposures and stacking them into one final image with special software.
I am using a trial version of Photomatix Pro, but most programs like Photoshop have the ability to align and stack mulitple images.

This is a whole new learning curve, but if you can manage one single exposure, your off to a good start.
