Dear lovely ZBrush-people,
I thought here might be some interest in this group here, as there are some extremely proficient sculptors on this board.
The premise is simple: Every day new themes are posted. You have 45 minutes to complete a sculpt, excluding rendering or whatever you want to do with the model afterwards.

Hopefully this can expand to be a community focusing on helping artists to grow and become both faster and better.
