So far we have just landing page: https://zeropool.network/ and weird logo of Guy Fawkes with ethereum logo in eyes. Which is too marginal.
Regarding the sketches, I don't think that I can give a good direction, because they are hard to implement, but you might try one of our ideas:
- Guy Fawkes Mask design
- 3d `Z` letter and text
- Chain of blocks separated by `Z` letter
