In a typical imageboard... you post image and a text.
This is normal stuff, kinda cool.
But what if instead of 'images', we have executable
scripts
in place of images. It only runs while the user is looking
at
it.
The script is executed by a JavaScript based interpreter
that is
emulating a custom fictional simple CPU (e.g.
DCPU-16 from Notch of minecraft fame)
This virtual machine can accept the viewer's direct input
if needed (text or mouse position), or it can retrieve
text from post in the current page (e.g. First post, or x
post relative to current post). [E.g. Rolling a dice
program ]
The virtual machine output can be either 'image based',
or text based output.
What opportunities does this allow for? Free form demo
scene on the spot? Etc...

Seems bit slow though, not sure if you want that for 'demoscene' lite [mofosyne, Jun 21 2014]

This sounds like Flash/ ActionScript. This isn't
specifically an emulator, but is sufficiently powerful
to make one. It's widely used for in-browser games,
including clones of NES games, etc. |

4chan + more interactivity = more disturbing. How
about web programming for the Oculus Rift interface?
On 4chan, that would be a 3D, 360deg view of
horrifying shock images. |

There are already Flash based imageboards (cue:
dagobah.net ), they are kind of okay, except
remixing flash files is a bit hard to do. With this half
baked idea, all source code is available to be
modified. |

How possible would it be to implement user scripts
directly in javascript, without the resulting security
implication... |
|
| |
So, nothing to do with the death penalty... |

One of JavaScripts functions is named "eval". You pass it a string of
text, and if the text happens to be executable code, the code will be
executed. Otherwise errors will happen, much as if ordinary
JavaScript code contained errors, outside the eval function. |
|
| |
The eval function is considered dangerous. You can't think of every
bad thing someone might ask it to do. That means you might regret
letting anyone write any block of code they might happen to think of.... |
