The Jelly Bean Easter Egg has been quite popular, for everyone running Jelly Bean and the other 99% of people who watched videos of it on the internet. The CyanogenMod team saw that, but instead of just keeping the mini game intact, they modified it a little. They replaced the jelly beans with small CID’s heads. Same concept apples: You flick them around. Good touch, this is pretty cool.
To access this Easter Egg, you go into Settings > About and quickly tap on the Android build number rapidly. Then long press the screen you get. There you are, enjoy!
