Shuriken has released BitTest
Shuriken has released BitTest, a free bitcrusher VST effect plug-in for Mac OS X. It converts your data to 8 bits, then you can turn the bits off (the top row) or invert them (the bottom row) individually. That is you can individually flip and invert the bits.
And that is all this little baby does, but she does it well.
Download OS X: BitTest.vst.zip
Download Windows: Shuriken will make a windows version when he get an incentive!
