Tetsu0: ?what's with the second twist??
It's 360 degrees, so the Mobius topology is preserved.
MuzzleFlash: ?Its called showing off?
O-ho-ho! As against the other strips here, mine took me about 5-8 minutes, and adding another twist was as simple as:
1. Scale the section by 0.5 vertically,
2. Copy it,
3. Paste Special,
4. Fix misaligned vertices if there are any,
Daubster: ?Very nice, Tetsu & Ant, but no-one's made the actual clean-looking thing, though.
I'll give it a try tonight.?
That'd be amazing in Hammer!
