Dmitry Avaliani was a Russian poet and palindromist, who made "important" contributions to Russian visual poetry. He invented and perfected the Russian ambigram, called listoverten'. This is a short text written so that after rotating 90° or 180° it is legible as a different text, or sometimes the same. Sometimes the two texts together make up one idea, and rhyme. He was especially interested in pantorhyme, anagram and other especially difficult ways of rhyming.
