.cc (Cocos Island) was used most famously by Arduino.
.cx (Christmas Island) domains were relatively common some 20 years ago, iirc because of some dynamic DNS provider.
And of course .io is the ccTLD for the British Indian Ocean territories

(For anyone who doesn't know -- don't go there. At least not while you're in public.)

IMO Arduino's use of the domain wasn't as famous as Creative Commons' use of the domain creativecommons.cc ... but Arduino is still at arduino.cc, while Creative Commons has moved to .org.
