alexreynard made an awesome ambigram for me of my name Sen Grisane. I liked it so much painted over it and experimented with layer effects. Alex did the difficult part ^^. Turn it 180° to see how it looks upside down.

Wikipedia says: "An ambigram is a typographical design or artform that may be read as one or more words not only in its form as presented, but also from another viewpoint, direction, or orientation."
