Kikkerland Clap-On Cube Alarm Clock • $17.90 • Yolk We were recently in need of a small alarm clock for our bedroom, one that was discrete enough to hide from view, but easily viewable when we needed to know whether it was time to wakeup. We happened upon this wooden cube alarm clock which fits the bill perfectly. Normally, the wooden cube looks like…well…a block of wood. But clap or tap nearby and the time reveals itself in red LED. Available in both light and dark wood, available online for under an Andrew Jackson.
