see http://amasci.com/holo/ Scratch-holograms can be made on CD cases using a couple of thumbtacks poked through a stick. Or get fancy and use a professional compass and black painted polycarbonate. Or automate the process with a paperclip stuck into a motorized electric eraser.

> Did you invented that by yourself?? Yes, but another guy discovered it in 1979, but he kept it secret. And in 1992 two scientists published about an accidental one similar to the "car hood hologram" caused by dirty lambskin mitts.

AHH! It all makes sense now! I made a simple one of a small "deeper" square inside a large "shallower" square and it looks great! Thank you so much!

> 1. What is the plastic It's a good idea to check out the website. Click on the URL in the text caption, or look at the video title. Plastic CD cases work well. Or lexan or plexi. > a line seeming to delve deeper in to virtual space? Yep. Vinyl records and CDs already do just that.

Just a couple of questions: 1. What is the plastic used in the video and where can one buy it? 2. (just to see if i understand the basic concept) if I make different size arcs all originating from the same point, the resulting image will be a line seeming to delve deeper in to virtual space?

Did you invented that by yourself?? Because that is amazing!

that ingenious! I didn't get it at first but you provided a great explanation. I can't wait to try! Thanks a ton!
