Want to run it yourself? The full Python source is below.

The complete, runnable Python source code of the ASCII artwork "HAPPY BIRTHDAY (Birthday Cake)". Run one file and a slice of birthday cake builds itself on your screen: the candle lights up, its warm glow flickers across the cake, confetti falls, and HAPPY BIRTHDAY pops in above, made only of letters, numbers and symbols.

The preview above is birthday_cake.py running live on a computer.

What's included

• birthday_cake.py: the complete source code of the animation (one file)
• README: setup guide, install and run in three steps
• HOW_IT_WORKS: how the cake, the candle light, the confetti and the letters are made, step by step
• LICENSE: personal-use licence

Requirements

• Python 3 with three libraries: numpy, pygame-ce and pillow (one install command)
• Tested on: Windows 11 + Python 3.13
• Expected to work, not tested yet: Python 3.10 to 3.12, macOS, Linux
• On macOS or Linux the HAPPY BIRTHDAY letters use a similar heavy font, so their shape may look slightly different.
