Hey cool!
I used to love buying PD disks of silly WB hacks back in the Good Old Days™. Ahhh... Lemmings on your WB, a guy cleaning the inside of your screen, upside down or melting workbench screen, bouncing mouse pointers, mouse pointer trails, eyes following the cursor, Neko running after your mouse pointer, cockroaches hiding under your workbench windows etc. etc.
Great fun :-)
Edit: I wish you lived in the south west so I could come and visit and play with OS4 ;-)
