MySQL backups with EBS snapshots. Assaf Arkin’s 45 line ruby script shows how to lock tables / XFS freeze / create an EBS snapshot / unfreeze and unlock, with hourly snapshots preserved for the past 24 hours and daily snapshots for the past week. Is an EBS snapshot enough to restore your data to somewhere other than EC2 though?
Temporary Mapping: Solar Decathlon. The OpenStreetMap default renderer supports start_date and end_date tags, meaning you can map temporary installations (in this case the 2009 Solar Decathlon on the DC National Mall) and have them automatically appear and disappear at the correct times.
