Decimator is a little effect plugin that consists
of a bit quantizer and sample rate reducer
followed by a LP/HP filter.

Madshifta is a very funky realtime pitchshifting
module developed together with Bram from
SmartElectronix. It allows you to pitch an
incoming audio stream in realtime with MIDI
notes or with the GUI controls.

A delay/feedback unit and a resonant LP/HP
filter are also included.

VowelFilter/VowelSynth is a collaboration
between SmartElectronix and Tobybear:
a plugin (synth and effect) for creating
vowel-like formant-filtered sounds.

CowDelay is a simple delay plugin with
internal multimode filter and other gimmicks
like ducking (delay only audible when input
is below certain threshold).

VST -Chess is the world's first chess game
for the VST plugin standard :-)

You have many configuration options,
different tile sets are included and you can
play against another (human) player or
against the computer.

DMOBag contains VST wrapper plugins for all
so-called DMOs (DirectX Media Objects) included
with DirectX9. You only need to have DX9 installed,
then you get two cool reverbs (one from Waves!),
chorus, flanger, gargle, EQ, distortion, compressor
and echo, all for free...

And they are even multi-channel capable, with up
to 16 input and output channels! For more details
see the included manual.

I made a VST plugin for each DMO, added a GUI
(see below) as well as VST parameter automation
and external MIDI CC control.

Don't complain about the quality of the effects
though, I have no influence on them, they were
coded by Microsoft, I just "wrapped" them. This is
also valid for the parameter ranges, descriptions
and features - the VST wrapper presents you just
the options and ranges that Microsoft defined.
