I started programming on my schools CASIO Graphics Calculator.

It was slow but allowed some text based games we then shared. No internet so did it all from trial and error.

Then ... i wanted a 3D Cube rotating. At 15/16 this was a bit too much i guess i had no idea about rotation matrices back then and deemed myself a bit dense.

Never got around doing 3D stuff at work, only databases all the time. I dabbled some with ThreeJS but i guess i was still haunted.

BUT THEN. Geometric algebra! So smooth. If you like tables and had problems with stuff like cross products or quaternions, didnt like copy pasting rotation matrices, etc. YOU WILL LOVE geometric algebra! It's like you meet 2 tables on a FK and bam its a volume (highly simplified!!)

Just my 2 cents. Don't write yourself off if you did not do 1337 demos in primary school on a tamagotchi.
