Arduino Smiley LED

Hello everyone.
So i was interested in arduino microcontroler and i wanted to try some project's. I bought my self an Arduino Mega 2560 of an Ebay and try to experiment with some LED diodes that are simple to do.
First i created a Smiley on the paper and made a hole for all of my 24 LED's. I have used some red, blue, green and white ultrabright LED diode and connected them to Arduino digital port from 22 to 53.
Then i wrote a code in Arduino editor some the LED whuld create somesort of animation.

The code can be found here:
