onesense

onesense allows you to create flash messages with background and color. Lot's of fun, probably a good idea to turn on the money-meter before you begin. And very useful - for example, you could use it as a tool for generating interesting article alert mailings and such. The Flash message arrives scrambled, looking like the one below...the recipient is asked, "Got the sense" and can choose either "Not yet, let me continue!" or "Yes, verify now" - the latter unscrambles the words, even if he/she was bluffing! Here's an example:
