255159 Dynamic Text Field

Disclaimer: I am not computer saavy so excuse my ignorance as I try to explain our need. We are seeking a script similar to those seen on custom T shirt sites. The difference would be to have the displayed text in a non-websafe font. The displayed field is to be dynamic i.e., auto justify, auto size, auto wrap, etc. (Someone said this needs to be done in flash, but I don't know...) As well, the entered text would need to be capture into a shopping cart. We are useing Agora Cart at this time but could change if necessary.
