I think that having a compressed version of the script(int .js form) would be very beneficial to those using the scripts on their website. I am using the effects script along with prototype (which really needs the compression the most) and I am almost to 100kb without writing much of my own code. There are other options to the script such as jQuery but they do not have the fully object oriented capabilities this script does. I have tried to use compression on the code but there are errors in the code which prevent it from compressing the rest of the code after the first 600(ish) lines. Please look into the compression of the code. A good compressor that I use for my other code is the w3compiler at http://www.w3compiler.com/
