Test drive this, I believe it's interesting but I need to hear from people with lower powered systems.
A potentially fabulous tool. My only quibble is (and I guess this is because it was ported from a raster program) when you break the effect, the result is a CMYK bitmap. Wouldn't it have been great if it were vector - think of the possibilities. I won't be using this tool very often.
Unfortunately, transparency only exists as a bitmap.
