have to say I'm pretty stoked about this Bryce 7 deal.
Here we were all lamenting its demise, and VIOLA ... Bryce 7 beta
Can it get any better than that other than its actual full release  ?

The instancing lab, although not complete as is, is really pretty cool. It would be nice to have a more predictable placement of objects and also a bit more randomness, but its a great start.
I did find you can utilize the random placement uin the EDIT mode , however, to change size etc, of objects. Very cool.

The IBL lab --- using the sky as hdri is pretty decent as well. Again, its not complete, but it works. Slows the render time down a bit.
