comment Why did Windows add a pointer trail feature?
@supercat: Windows sets (or tries to) a particular set of parameters with DrvSetPointerShape. The driver then returns a value to indicate whether it can support those parameters or not. The parameters include both the length of the trail and the frequency at which it should be updated. So, it might support (say) up to 5 frames in hardware, and any more than that would switch to software.

comment Why did Windows add a pointer trail feature?
@DebugErr: That's frequently, but not necessarily true. A display driver can support mouse trails directly, and if it does, Windows will use that. Many don't, in which case Windows will render the cursor in software. Here are some of the details for anybody who really wants them.

comment Why is the mouse cursor slightly tilted and not straight?
@AlbertRenshaw: ...at least if you assume square pixels--but that wasn't a given in those days (e.g., it wasn't normally true of an EGA or Hercules card at their maximum resolution).

comment Is this rotating cube interface user-friendly?
@Peter: Faster would help a little, but I think to really do the job well, you should make the movement more random.
