Thanks! It didn't occur to me to do a search under 'all' free stuff. Silly me. I found a few, we'll see how they work. I don't have Bryce, unfortunately, and neither the budget nor the hard drive space even to think about it, much though a nice Brycely rock is precisely the sort of thing I was thinking about. Honestly, though, I'm having a wonderful time but I'd rather be whistling in the dark. ;)
