@brodiss: Interesting thought.... I might just do that. What do you mean by dots? The darker squares depicted above are the "snake" if that's what you mean. @bigbadelf: shrugs I just didn't know exactly what you believed. YMMV? @wildman2: Err.... nooooo. Snake. shrugs again I like snakes better. We used to have some as pets. They're really cool. Especially as pranks...... evil grin
