You could use a .gif with a high frame rate, you can get them really high, but only a few browsers would be able to display it (Mozilla Firefox would because it shows .gif files with whatever frame rate, but IE slows down the frame rate). However small messages like that don't work very well and won't make people do anything. But if you do try it, I'd warn you that you could face banning due to "Forum Abuse: Do not abuse features of the board (such as MyCode and the Shoutbox) to do malicious or really annoying things." - having images in an avatar or signature is a feature and the subliminal messages are annoying = banning.
