Ambigrams

I came across these ambigrams by Tiffany Harvey during the big Christmas/New Year break. There are some great examples in the gallery (on Flickr, of course), but these two caught my eye especially. I’m fascinated by ambigrams, and always thought words suitable for making them were fairly rare, but Harvey seems to promise any word can be made into an ambigram, even two, three or four words. Fascinating.
