A music player - Has no source for the player and a few bugs. But it's easy to interface from *any* language with support for SB and GUS. Rename file heartq.002 from Iguana's demo HeartQuake to demovt.exe and use that instead. It's version "1.6"

A collection of sources from Inconexia - A collection of effects. Get gallery.zip for the museum part which the .txt file says won't be released. :)

The voxel landscape from Heartquake - No explaination of the effect, non-recompileable. The code is largely dependant on code libraries that the coders have developed and is thus somewhat difficult to follow.
