The paradigm with kitchens is that you wash ingredients in the sink, do prep on the counter, then do cleanup in the sink. Japanese company Toyo Kitchen Style proposes an entirely different workflow with their Zero Flow sink. "We believe a truly user-friendly kitchen is one with short cooking paths," the company says, which explains their design.

The sink is enormous, at 76cm (30") square. In addition to its sheer size, the sink's key innovation is its staggered ledges, which support a large cutting board/worksurface and a perforated tray for draining.
The idea is that you've got enough room in there to do everything except the actual cooking. The demonstration video is in Japanese, but there are English subtitles available:

Well thought out and very usable design. Japanese restaurants have been using such designs for years. Excellent for cutting fish when running water is needed. Just make sure to use a good strainer in the drain below.
A better solution than the divided double bowls. I hacked an ikea full depth sink basket inset over a single bowl sink. Works so much better than the double bowl we had.
