One of my hobbies is ambigrams, the term coined by Doug Hofstadter for writings which can be read in more than one way. I've been doing ambigrams for more than 20 years and I do most on paper. Here are a few I've done on the computer:



Scott Kim's web site

John Langdon's web site

Punya Mishra's web site

Robert Petrick's site
