Hi there,
I tried to create some unique shape with alphabets with the following codes. But i have to keep change the string variable manually. Is there a way to change the string input after i run the code? Means after i run the code, it will output the default unique shape, but when i key in any letter or symbol, it will over-write the previous string and display the new unique shape with the new string input. I tried to name the string and using keypress function, but it does not allow me to do so. Please advise me. Thanks.The following is the code:

Hi there,
I would like to create a font that will change it's shape when i move the mouse. Anyone has any idea how to create it?? I've been trying this for weeks but still can't find any solution.
The following is a tutorial code i found on the site, i want to create something similar. Instead of turning 360degree by itself, i want to control it by the mouse movement, and the font will only change it's shape when i move the mouse.
