Reuters had an article this morning about the Rochester Cloak, which was created by some smarty-pantses at University of Rochester. The article links to a UoR article that shows you how to make your own. One of the articles mentioned using the device on a semi truck trailer so you can see what's behind you. Makes me wonder, "What would I use an invisibility cloak for?" Hmmmm!

| Looks like fun indeed. Main problem is to get the lenses I suppose... |

| My problem is that I'd probably try using it outside and the lenses would accidentally set me on fire. |

Inexpensive lenses of known focal length can be obtained from places specializing in supplies for stereoscopic photography (used for building stereo viewers). Look about half-way down the page here for an example ...

This place if you're in the US. The time I actually needed lens elements, though, I bought a broken and obsolete 50mm lens off of eBay for $8 shipped. Ebay would be a little harder if you're looking for matched pairs, I suppose. |
