Haha,
demerphq, I should confess that I did actually peek in side the 'black box' ;/. Initially, I couldn't figure whehter your shaded area was for practical or purely 'artistic' reasons ;-).
Actually, with the code you provided, I wouldn't be surprised to see funky output produced by the Dumper. However, I wouldn't expect what you just showed to us, either. Thanks for sharing this with us! ++.
