Yup, i know, its alot easier to make this then most peoples think, the laser pen settings has a bar that has 'cutter\, click that and you has a lightsaber that cuts.
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?
Yah on TV, I learned what the SS were and what the Swastika really was as a symbol of good fortune. Pretty much a very good flag for propaganda during the war to influence those of his country. They also say he took up a different look and started adapting the special colour of red adapted from U.S.S.R. Propaganda. Anyways, its a nice model.
I forgot to say that Hitler tilted it to the right to make it have a different meaning of evil, twisted ideas and deeds he was to do; as said in the documentary.
