Interesting idea! I had to think about what you were describing, but that actually is very similar in spirit to the experience back then.

It's kind of like discovering the assembly monitor on the Apple ][, which you could get to by poking a value in Basic. I remember typing in an assembly program I found in a magazine that sampled audio from the cassette recorder, and played it back on the speaker. It was gritty sounding, but an amazing discovery for me at the time (about 1982).

(I'm always doing Ctrl-Shift-C to copy text from the browser when I forget I'm not in the terminal anymore--which brings up the element inspector and the console. I've always wanted to explore it myself, but I'm usually deep into another project.)

I wonder what I could have done if I had Three.js?
