Step 9Go out and tag something! (and report your results)
If you followed this instructable to the end: Congratulations! You just made a device with great potential for light graffiti.
Now find a nice big wall in town that just calls for esthetic improvement trough animated laser tags!
Take a camera with you and record the fleeting images with a long exposure timlight graffiti expressions.
I hope i have described everything clear enough! Do let me know of your success or troubles while making and using these.
The Arduino code will give you a head-start. The patterns are written as series of coordinates to let you add new ones. Many improvements are still possible in the code. I suspect the quality of the picture and complexity of possible shapes can be much improved with somewhat smarter code driving the actuator.
You can experiment with other signal sources, stereo music players will probably be interesting.
Another idea for improvement you could try is to control the laser power with the Arduino too. This way you could program discontinuous patterns by turning the laser on and off at the right moments in the cycle.

you could try using audacity to make some 2 channel custom waveform sound... it's easy to use! read manual
and for real-time control something like pure data? it's great fun playing with it, just don't be intimidated by its looks. read manual
i see you needed an amplifier, how did you hook that up?
