Massage
You looked too long on the screen from an uncomfortable position, and now your neck is not moving anymore?
There will be donation based massage by the muscle hacker guy(s). Donations go to haxogreen. Suggested price is 0.01€/second.
Inquire at the Infodesk
As Yoga is a related activity, there can be massage added as a bonus after.
How does this 1ct/s donation work?
Currently not at all. But if someone could build a little seconds counter or an app doing this, that would be great. Not a MM:SS timer, but an SSSS timer, to be converted into SS€SSct. If not, donation will just be approximate by your wild guess.
