Oh, goodness, me oh my. I thought I might just go and mess up a few corporate logos for fun and for experimentation. I did some basic photoshop filters (displace > twirl) and made some famous logos into captchafied versions. Scope it!
Above: Castrol, Seagate and Microsoft logos.
Xerox, citibank and Oracle logos.
