    Thumbs up

    NICE! The only thing I can suggest is to get better at drawing... I cannot imagine it being easy to draw on a ten storey building though.

    Question

    So, the dot from the green laser pointer is tracked with a camera, and then the image is projected via a high power DLP video projector?

    I hadn't seen the magictouch system. We were using the free software available here:

    With some other info here:

    My setup used a 2000/4000 Watt inverter (hooked up to 2 cars in parallel), a 6500 lumen projector, a modded leadlight, a firewire webcam, and my macbook pro.

    Cool

    Not sure that a 20 watt laser projector would do you any good with that setup... The laser is only used for tracing the drawing. The actual graphic is displayed with a DLP projector. You wouldn't be able to get the "dripping paint" effect if you were using galvos and a laser. Oh, I suppose you could do a raster-scanned image using an AOM for your horizontal scan, but then you'd only have a couple degrees of scan angle to work with. Nah - DLP is the way to go there...
