My two kids have been going nuts creating Lego sets for themselves with the Lego Digital Designer.

It’s a great idea. They use the software to design their dream Lego creation, just be clicking and dragging pieces onto the stage. They can even rotate around like any good design software.

Then when they’re done, Lego calculates a price, boxes it, and sends it out complete with assembly instructions.

Totally user-generated made-to-order, and great use of the web.
