A coin operated game may seem like a toy, well, it is, actually, but with so many tasks running at the same time it's the perfect socket for a multi-core processor. A coin operated game (think pinball)must process lamp effects, music, sound effects, solenoids, switches, run the game application and still fetch data from USB or other memory. We usually used an operating system to handle all of these tasks, but with the multicore propeller one core could handle the IO with one core, another core for the music, another for the sound effects, another for the lamp effects, memory, game, and even one just running debug functionality with video out. Sure, not every solution requires a multicore processor, but if you're using an operating system to juggle tasks, a multicore processor might be a good solution. Give the propeller a spin, too. Parallax has some great kid tools to get started and the processor is quite capable of handling some hefty processing.
The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
