thanks all. plans for little yellow are loose, but will definitely post some renders once i get some more time to play with it....
Fernando, silo is great for intuitive modeling and modeling from sketches (for me at least) but i haven't yet used it exclusively for archviz.... still stick with max to compile all archviz scenes(especially when building from dwg's), although i've been getting real comfortable using the silo interface... everything from the screen shot was built from a few cubes...
give it a spin, it's like sketchup on steroids:
