Found this over at Nintendorks in the DRCs, figured I'd share it:

Click on the rows to change them vertically, then they will "rocket" up and off screen, unless they are too heavy in which case they fall back down... you can then adjust them as they fall, or do whatever you want with them.
It's rather buggy, but it offers a taste of what the game will offer.
