All I could find was cgi images of the red one.
There is this white one that was used in the original indiegogo campaign. No idea if it was a mock-up or a working device but it looks like at least one was made.
This was the first design, but i am sure was never released.
@krogothmanhattan, as far as i know the one i sold you was the only version Mycelium released of the entropy device. I think there was about 1,250 sold.
