I think such a machine would be a godsend to us. I know that I would love to be able to dump bucket after bucket of Legos into a machine that can then properly identify the shape and color and sort that piece into various sorting buckets. and then catalog all those pieces into a master database. Would be awesome to then be able to cross reference a database that could then look at the pieces you have and tell you that "you have the proper pieces to build this and this sets so you can identify the sets that the pieces came from. Or at least let you sort and catalog your massive collection of random legos and then have the database let you know what kinds of sets you could make from those pieces.
I'm just wondering if such a device could be made fairly easily with the technology that is available to us now?
