Algodoo

you can remake that it actualy works next time-.-

I need to figure out a way for laser surface scane display by laser surface contactr. I had an idea of a laser that not only displays laction but displays the surface which the laser comes in contact with, somewhat like sonar but the laser represents the sonar sound waves. It could possibly use some kind of main bar that moves across a display screen which displays with tracers in which it collabrates with the laser contact and spawns and moves the tracer to form a temporary picture of the surface scaned by the sonar laser. Maybe you could try this concept?

Also cedwe, i think you dont have algodoo because you need the lasers for it to work.
