Only 4 angles of rotation in manual mode.&nbsp; No real manual control of tilt, but you can pause the auto-swirl.&nbsp; What’s needed is a fixed angle light with the user having the ability to tilt and rotate the coin in tiny steps, same as done when grading with coin in fingers.&nbsp; This is much tougher and more time-consuming to program.&nbsp; Basically, the coin has to be recorded and indexed when put through all rotations and reasonable tilt angles.&nbsp; This can be done robotically. Then an interactive program needs to be able to bring up any tilt angle and rotation the user wants from the recording.</p><p><br /></p><p>For those who find it dizzying, continually tap the pause/play button for auto-swirl at a rate you are happy with.&nbsp; </p><p><br /></p><p>Cal[/QUOTE]</p><p><br /></p>
