BlockCAD

BlockCAD is a free program for building virtual models with Lego-like bricks. You can save your models, save pictures of them, or reuse a complete model as a part in another model.Everything can be controlled with the mouse, but it's also possible to use the keyboard for most of the commands, making 'routine building' more effective, and there is a minimum of text involved, to make it easier for children. Download BlockCAD for free from http://web.telia.com/~u16122508/proglego.htm
