All I can say is thank god (aka Tom Sederberg) for T-Splines. I am doing a project for a client today which is a military style logo crest button. On it there are 2 lions, some twisted rope with sculpted metal brackets, and a jeweled crown. All details must be modeled in a false perspective. Would be a real b-tch if not for Tsplines. My workflow goes in this order -

sculpt a mesh grid in Modo for basic shape
retopo in Hexagon
import to Tsplines

Sweet! I wish I could publicly show this work in progress. But this one is under wraps at least for the next few months. It's gonna look awesome though... :)
