[*] Badge

Besides being a ticket, your badge can be used as your mental state indicator:

Green - I am feeling great!
Blue - feeling low, might not be my usual self
Red - I am overwhelmed, give me some space

To control your badge you can use the M, A, D buttons.
M - changes the brightness level.
A - turns a special effect on/off (needs unlocking)
D - change the effect.

You can interact with the badge via USB (com port).

The badge is hackable, technical information to help with that will be shared after the conference.
