I present to you Dr Tyme: the result of one iPad, 2 hours, and an invite to a Hero or Villain themed 30th birthday party.
Strapped nimbly to my chest with some blue ribbon (can someone please go and make an iPad chest harness?) I had my iPad (v1) running iCab browser in full-screen mode (with icons disabled and 0% opacity). Airport mode meant the battery only dropped 40% in over 5 hours.
The clock was made with some CSS radial gradients, the hands with transformed rectangles with border radius, and the pimpin dollar sign set in Kulturista Bold.
My super power? Messin with time, yo!
Single tap to stop time, 4 finger tap to turn back time, and 10 finger tap to rock the house.
Take that Flava Flav! You aint got nothing on my neck clock, boi.
