Windows memory management (Layer 0) and compression/decompression of the assets from the slow 1X CDROM that it was targetted for. 

-------------------

Yeah, that was a long time ago.  The resources were compressed using an inhouse compression that basically tried out a bunch of different compression types that I identified: like run-length encoding, Lempel-Ziv, etc.  Each resource was compressed with multiple techniques that would result in the smallest file along with the quickest decompression.  About all I remember about the encoding was that it had a header of type and size used between the different encodings of a resource.  The header was bit-level too that varied based on the information needed.

As to source code, when TerraGlyph development was "dissolved," the founder and I were under heavy legal pressure from the investors to not recreate or use any of there code.  So I doubt that the close is in the wild.

Yeah, I wrote most of the compression/decompression code and pretty much only remember that it was composed of a bunch of different compression methods that were identified by a short header something like this:  compressionMethod::length::compressedBits...compressionMethod::length::compressedBits... etc., etc. this was on a bit level too so you might be able to experiment with some of the beginning parts of a file to see if you can figure it out.  One of the compression methods was RLE (Run Length Encoding), so as an example, this
010101010101010101010101010101
could be encoded as (if RLE id was FF) FF::0A::01... again, this is a made-up example but represents how I implemented the resource encoding.  My suggestion is to look for patterns on the BIT level... I know we were surprised at the amount of RLE that could be done on our image files.

As to the investor, he was one of the Chicago Waste management owners (think Sopranos).  It came out later that TerraGlyph was mostly a money laundering company that was never supposed to make money and set up as a sub-company of a larger shell company that actually owned the intellectual properties.  I have no idea where the assets ended up after the development part of TerraGlyph was shut down.

Good luck...
