These are incomplete designs for software (or, occasionally, hardware) that I would implement if I had the time or the stamina. Not all of them are completely serious. (For even more half-baked ideas, and to publish your own, visit the halfbakery, www.halfbakery.com.)
Audio output, motion input.
Hardware: a touch-only interface.
Hardware: a travelling clock.

Your electronic dead man's switch.
The URL market
Offering high-demand, low-supply resources without getting run over.
Loose ideas for a frontend for reading and answering e-mail.

Nelson thinks about distributed systems, cryptography, and small, neat things.
Elliott Evans' Brainstorm File
Short, technical, mostly computer-related inventions (but with a wonderfully surreal first item.). The whole subtree is well worth exploring.

Interesting articles (and great inventors' portraits) from old and recent history, if you can stand the distinct US-American bias and the inexplicable respect towards Bill Gates.
Jaron Lanier's Video Feedback Waterbed
Ought to be invented if it didn't exist already.
