I figured out a long time ago that the thing that makes a toy successful is the level of interaction with a child and the ever changing experience one can get from said toy.  In the world of technology where kids are demanding higher tech devices something like this has alot of promise. Not only do siftables have that edgey feel to them sort of like a new apple product they also show promise of simplist to use and a large audience.   If the developers of siftables were looking for investors to start I company I would glady do it as I am sure they will be the “must have” thing in a few holiday seasons.
