Symmetry without screwing up UV's

[Wegg]

Not to beat a head horse here but I would love to point you programmer types to an implementation of symmetry that looks really awesome. Far better than Lightwave's and, obviously a zillion time's better than Wings' UV destructive method.

On their front page towards the bottom is a feature video. In that video at about the two minute mark you can see the symmetry mode being enabled. Pretty standard. But THEN. . . he enables "Topoligical Symetry" Mind blown. . .
