Suggested projects for older wireless routers?

I'd like to hear your ideas on what can be done with old wireless routers? Any projects you can think of that could reuse the antennas or the internal circuitry? What of the cat5 or USB ports?

The older Lynksys routers can be flashed with dd-wrt and used as excellent WiFi repeaters. You can boost the power considerably and get amazing WiFi distance all over and around your house.

Depends on the old wireless router. Some of the Linksys routers (not all) could be converted into small Linux-based servers.
