HI
Next week will be uploaded what is missing to see the complete network. The sculpture itself is mining the currency each time a coin falls, when this happens a trigger is activated and then 2 raspberry pi 3 begin to mine inside the mill.

The mill will be the only one producing/mining TEIOS, this currency is going to be possible to be mined until the end of the ICO.
