I loved the sticker/water-bottle/NFT thing at ETHDenver, which incentivized hackathon attendees to talk to sponsors.
What it does
It's a scavenger hunt. Users people search for other people at the hackathon who hold a given token. If they find that person, everybody who passed the bounty gets a share of the prize.
How I built it
Challenges I ran into
Changing projects saturday night :(
Accomplishments that I'm proud of
The contracts work really well! Even if the UI is bad.
