There are a couple of techniques that have been used over the years that 
I can't get my head round.

*Assume 2D hardware*

1st the rotating tower effect in Nebulus, it would be easy in 3D but 
that wasn't available on the spectrum, c64 or even Amiga

2nd the scrolling road that they used in poleposition which was flat, 
outrun which went up and down as well

Any ideas?
