well... Actually, this isn't ofuscated enough..
I mean, I pasted code in my favourite editor, squeezed my eyes a bit, and I could see the output with difference of patterns... just highlighting "\040" showed me I was right, and executing the script proved it...perhaps having a hash of many elements to recode a char could be better (like a a multipattern substitution code)...

Good luck for the next ones!
