Animated Wall Clock using Processing Programming Language

Hello friends! Meanwhile I was learning “Processing” programming language and was trying out my hands on some cool experiments. In this post, I want to share with you the processing code which I wrote for an animated wall clock.

By the way, Processing is an open source programming language initiated by Ben Fry and Casey Reas at Massachusetts Institute of Technology (MIT) during 2001. You can learn more about this platform at their official Website. If you are unknown to processing environment, then do visit their site and learn this language. Processing is cool to learn.

In my processing code for animating a wall clock, I have made good enough use of axes translation translate() and rotation rotate()  feature of processing. In my computer, the clock rotations are in sync with the correct timing, only when I use 6 frames per second speed. This frame rate may vary depending on your system configuration.

My code for the wall clock is given below:
