Lumion is the more easy and funny Prog that I have seen!
Absoluty crazy and a "game boy" UI !
Ocean, snow, wind, clouds, terrain creator as like Zbrush, pets, personnages, vegetations, still renderings, animations etc...astonished
You win a factor 7 for architectural Projects rendering against other progs !!!

The only problem is the price! Hoppefuly a free version exists for Hobbyst ;)
