Hello!!
I found this challenge that could be interesting for you all.
ARM is running a video and photo contest - 'Show Off With ARM' - to showcase ideas for improving lifestyle with ARM-based technology or how you are building a more efficient embedded device with ARM-based solutions.
The winning submission gets a Samsung Galaxy Note 3 and Samsung Galaxy Gear smartwatch.

The deadline for your entries is Nov 15th, 2013!
Just as reminder, the Rasberry-Pi is ARM based! :D
Cheers,
Dan
