Please see this this January post for an overview of Pajama.
Pajama now runs on Java 1.4 and up, not just 1.5, thanks to Retroweaver, a class file rewriter.
The Pajama site is much prettier & friendlier now, thanks to Holly. She organized the image effects into several groups (with overlap), chose settings to show them off, and added “toy tips” suggesting what to try.
I would love to get comments and suggestions.
