All your turrets have such pleasing lines. I'm really digging the last one. The mechanical shapes mixed with the floating elements are an interesting design!
cheers for the recommendation, but... what are the examples based on? Its not all just floating heads and characters, is it, sort of hoping for some more environmental stuff as well.
Are you thinking sphere as in Quadsphere? We've had a few threads about them, there is even a primitive plug-in floating around somewhere made by a PC'er.
