Hi,
I wonder why every free email account creation check has a static image to ensure that the subscriber is human. Why not animate the image (gif, flash, whatever).
Humans will still recognize the text on the image.
It would be even secure if you morph texts (“apple”->”scyers”->”semi-independent”…) and ask the wana-be-subscriber to enter the second/third/Nth word.
