Remigiusz,

you do not need to make excuses for "disturbing" the list. i know it
seems like it’s asleep most of the time but i’m sure most members would
like to see it a little more awake.

now to your questions:

i only recently added the note about the availability of the other size
cubes, so it’s not surprising that you missed it.

the reason the windows version doesn’t support other sizes is because
the Direct3D library i used would mysteriously crash when the user
attempted to change sizes. i never did figure out why and sadly just
removed that option.

you are right that the question about screen rotations in the linux
version is connected to the edge length question, though i don’t know
how you could have guessed that. ;-)
the reason is because the linux version uses full 4D->3D->2D projection
and don didn’t want to have to implement the extra transformations to
perform rotations. in my case, since i was using Direct3D, i only needed
to do the 4D->3D projection and let D3D do the rest. i still had to
implement a quaternion object to produce the rotation matrices for it
but that wasn’t too hard.

oh, and if you do translate and publish royce’s solution on the web,
please post the url here and i’ll link to it from the MC4D site.
