Bring the Razer Hydra back without Sixense's unmaintained SDK: build on VRPN's open driver, read and record its streams, calibrate its magnetic tracking, replace its default gamepad mode, build a 3D viewer with record and playback, then map its two controllers to OSC, MIDI and two players.

Bring Essential Reality's 2002 P5 Glove back into use without its vendor's software: find what may legally be used, read its streams, calibrate them, switch off its mouse mode, build a 3D viewer with record and playback, then bridge it to OSC, MIDI and a game device.

Bring Sensel's Morph back on an Apple-silicon Mac without Rosetta or Sensel's closed libraries: build its open driver natively, read its pressure images with the open Liberation decoder, learn what each overlay makes the firmware send, and start with the gaming overlay before trying the drum pad, plain, Buchla Thunder and Art overlays for games.

Swap the Gametrak's own circuit board for your own microcontroller, wired or wireless.
