Weak, not ready. Unusable
GUI has potential but it is not ready for prime time. Spelling errors, unexplained buttons, and worst of all the option to set your cube starting position with the camera (finds the color orientations) is color blind. I’ve tried it in different lighting, with different backgrounds and it doesn’t work. My best luck was letting the colors change (think slot machine) and trying to hit the button when they were momentarily correct. However, that too fails because there is no way to repeat a side that didn’t work without starting over from the first side.
