4 spheres in the same plane, 1 cube for environment and a nice
texture_map... the old demo of reflective sphere on checkered plane was
quicker 25 years ago.

Woo! 0 FPS. :-D

Still, it's kind of impressive that an interpreted language can do this 
at all. Kind of like the way my sister's old laptop can run Doom under 
Linux under a PC emulator under Windows XP, and it's *still* faster than 
it was on a top-of-the-range 486DX when it was released...

javascript is JIT-compiled to native code in many modern browsers now, like
Chrome.

I saw DOOM ported to run on a graphing calculator, running real time. Wild.

I have a graphing calculator. I'm not sure if it's a Z80 or a 6502. What 
I do know is that you can't program it. Oh, there is a "programming 
language" for it, but all it allows you to do is automate a series of 
key presses. That's *it*. You can't, for example, write a program that 
generates a list of data, and then plot that data.

Still, what do you expect from Casio?

When I was finishing school (around 1998) the TI-86 was the most popular 
calculator (I think our school got a special deal somehow and almost 
every math/science student bought one).  You could program it directly 
either in some BASIC-like language or assembler, or you could connect it 
up to a PC to download stuff.  I remember someone wrote/ported super 
mario for it, it took a while for the teachers to realise that people 
had games on their calculators!

Yeah, I gather the TI calculators are the ones to have. Proper CAS 
functionality, true programmability, and all sorts of other good stuff. 
Same about the price tag, eh? ;-)

I'll tell you: it aint in firefox, that's for sure. If you want to bring 
the browser to its knees, just load that page.
