Palindromes are by no means human inventions. The genetic code is littered with palindromic sequences of nucleotides, some of them known to have critical functional significance.

Proposed application of this font: AMBULANCE, POLICE signs, highway info, advertisements, seen from the rear-view mirror.

@Neoqueto: An example picture with a rear-view mirror? It would show the text reversed back to normal by the mirror, so what's the point?
