A demo video of the Minecraft Alchemical Cauldron plugin (v0.2).

The plugin is now available via Bukkit: dev.bukkit.org/server-mods/alchemical-cauldron/

Some old details are here, but this is probably obsolete: forums.bukkit.org/threads/fun-alchemicalcauldron-v…

Or find the source and distribution on github: github.com/georgedorn/Alchemical-Cauldron-Minecraf…

You can find all of the block/item types within the Bukkit source code. See github.com/Bukkit/Bukkit/blob/master/src/main/java… for more details.
