Also, you're not just limited to your own creations. You can find buttons art from others' collections, follow creators you like, receive streams and send conversations. And yes, there are paid buttons -- you can donate to a cause at the same time as you endorse it. The button might even get you out of trouble, as you there's a panic mode that will send an emergency message and your location to as many as four other people.

The BEAM button is available now, but there's a catch: it's $99. That can buy a lot of conventional buttons, and those won't run out of energy. You'll contribute $3 to a charity when you buy, though, and this is certainly a viable option if you'd rather draw your own artwork than track down an elusive button that expresses your exact thoughts.
