Cool. Beginning to see quite a few visualisation projects in recent months, always refreshing to see new contributions. This looks familiar, can't quite tell as could not seem to enter my own values. Tried addresses, also tried transaction IDs but it still just shows me the default (?) 83080 block images.
Want to test out how the visuals look for some mixers, could be interesting;)
Search by address is not implemented yet. But you still can search by transaction hash (DB might be a bit behind on latest transactions)
You can also pass transaction hash in URL like
