Reflex Paradox Trackball Controller
Trackballs have devoted followers amongst computer users, and are most often found on the dedicated consoles used to grade and color correct films and TV shows in post-production. Where they never really caught on was gaming, despite the efforts of companies like Reflex who created an alternative to the PlayStation DualShock controller with one analog joystick replaced with a big red ball. The Paradox was designed to offer the same level of precision and control a computer mouse did for certain games, but the use of trackballs on controllers never really caught on.
