I'm hoping you experienced Robot and Laser builders can help me with some brainstorming for a new project. I need to turn a "robot" to face a human. The human could be carrying an iPhone with GPS, ultrasonic sensor, laser reflector, anything small. Within 15-30 degrees would be close enough...

Thanks everyone for your effort! I will start experimenting myself. Do you have any diffraction links to add to the one below? Which did you purchase? Matrix? Line? Starfield Laser Diffraction Grating Kaleidoscope | eBay

Made one in college decades ago. Who will be next to try?

I'd like to see it! Please do post a picture. Anyone else?

Those are definitely not random looking. But can I replace the laser inside?

Maybe they Photoshopped it?

That's exactly what I'm trying to figure out! How do they do the garage door so randomly?

I've got many lasers. Will it look sorta random or a distinct repeating pattern like wallpaper in the bathroom? How can I make it more random like stars in the sky? Moving of course. Mechanically how do I rotate both? Thanks for the quick reply!

BlissLights Spright - Amazon.com What kind of diffraction gratings does this require? 2 of em? Where can I purchase them? Ebay? Cost? Is there another method to generate many 100's of beams from 1? How about just 10 randomly XY spaced dots? Which method is most efficient for power output...
