Image regex (Score:1)

Hahaha... if the regex allowed moving to any adjacent pixel, you could write a regex to solve a black-and-white maze image ;)

So going from the red starting pixel, to the green ending pixel travelling only on the white paths:

print "yay" if ($image =~ /\N{red}\N{white}*\N{green}/);

That would totally rule! I don't think mapping an image to a string would quite be feasible if you allowed adjacent pixels though... unless the string was lazily generated or something... wow - crazy thought!

  The idea of being able to move to any adjacent pixel reminds me of Befunge. Don't go there!
