About About by PCalc

About by PCalc is the former About screen of our scientific calculator app PCalc. It was partially an excuse to learn how to program 3D graphics, but mainly I wanted to make the most fun About screen ever. It started just as a 3D icon that you could play with and throw bananas at, then there was a little car you could drive around, and soon there was a whole city to explore. It's kind of a toy, kind of a game, and kind of a window into my subconscious. Anyway, it got a little on the big side, so I decided to spin it out into its own app. Just explore and see what you can find, and be sure to visit The Castle of the Panda King! You can play using the on-screen joysticks, but it also supports gamepads and keyboards.
