Because M-Blocks can not only autonomously propel themselves but attach to one another in an infinite number of configurations using relatively cheap mechanisms, there is a lot you can do with this technology. Imagine, for example, dumping a container full of M-Blocks on an empty lot, then sending a signal for them to self-assemble into a house. Or imagine telling your couch, which is made of M-Blocks, to divide itself into three chairs instead, or transform into a bunk bed to accommodate some surprise house guests.
