A digital time capsule. Write a letter to someone you love and it's sealed with timelock encryption until January 1, 2050. The key doesn't exist yet: a global network of institutions (drand / League of Entropy) will create it that day. On Dec 31 the capsule closes in a "Midnight Wave" around the planet. English, Spanish and Portuguese.
