Mike Trinder has taken over development of this really cool tool from Bach, and has released a cleaned-up version with a bunch of bug fixes. This is just the core program-if you want other cool effects, look for them separately. (Try searching for Mike's stuff, or for Chisel stuff.) Also available is an effects programming kit (updated!), for use with either Codewarrior or Think Pascal, for those who want to roll their own. Latest update allows Chisel to be used easily with 3rd-party scenarios (like Evil and Tempus Irae). v2.1.4 fixes a long-standing (but unnoticed) problem whereby Chisel would wipe out a map's resource fork. 2.1.5 fixes a minor bug involving the tab key. 2.1.6 is totally unnecessary for PPC users... it simply fixes Chisel to work with 68k Macs. (If you don't know what a 68k Mac is, you can stick with 2.1.5.)
