Friend of the site Bence Dobos pointed me to this. First of all I had no idea the TI-83 could do things this nice now-a-days. Secondly, this may be even better than ASCIIpOrtal:
It could use scrolling screens and the portal view I used in ASCIIpOrtal. And color. And sound. But this demonstrates the amazing things happening on the TI Calculators, still very much the tinkerer’s playground.

That’s awesome. I remember someone showing off the TI-83 version of Doom back in the day.
With all the math behind Portal, how appropriate it is to be ported to a graphing calculator!

Awesome write up explaining the physics.

I didn’t have to deal with this in ASCIIpOrtal because it was tile based.
