I've seen it done, but it's not easy to get a lot of detail. You
could rough in the bleachers, but I doubt if you could get tiny
players to scale.

Beats me, but I hope you'll post if you succeed in doing it.

If you supply clean files, do your own post-processing, and buy at the
cheap end of the scale (I believe that's still ZCorp, or ThermoJet if
you can use a part with hair on one side of it), it's _almost_ true.
But if you own your own machine, I expect it's better than true.
