Andrew Hicks, a mathematician at Drexel University, have created a mirrored surface that is bent in a way so the image you see is not reversed (not a mirror image).
From the New Scientist:
By calculating how to vary the way each of tens of thousands of points on a mirror's surface reflects light he can create mirrors that do amazing things. For example, reflecting text without reversing it or capturing a full 360º scene without distorting objects.

a lot more work and this could be used to create invisibility cloaks surely.

Anyway, the SPS from UTexas did a lot of work on this a couple years back, and some of it is published here:

It explains well why they can't be seen close-up. Personally, I'd love to see them if I were in the area...meteorological phenomena are awesome!
