Happy New Year! or Demoscene on the calculator

I wanted to give everyone a gift for the new year, and what gift could be better than a demo?
Yes, not simple, but a New Year demo for a graphical calculator.

Casio fx-9860g for which this demo was made, has a monochrome screen with a resolution of 128 * 64 pixels, 64KB of RAM, and a processor with a frequency of 29 megahertz.

This demo is written in C (without pluses),
Display resolution is not very large, but it allows you to keep a good fps.
I hope you enjoy this demo =)
