Hi. We've developed a wearable 60-LED circuit board watch run by an ATMEL SAMD21 (ARM Cortex-M0+). We had a lot of fun developing it and have been really impressed with what's possible with ARM.
We've launched a kickstarter for the project and thought that it might be something of interest to the community!
