A collaborative pixel art experiment

8192px - A collaborative pixel canvas that grows over time

8192px is a little pixel art experiment for the web where users have to work together to fill out the canvas as the timeouts in-between being allowed to place a pixel makes it hard for a single person to fill out the canvas.

The rules are quite simple:

• The canvas starts out at 2x2, and grows by 2x2 every 8192 seconds of users being active.
• After placing a pixel, a user must wait a deterministic random amount from 0 to 8192, the scale of the value depends on the number of active users.

Mouse and keyboard controls:

• Click and drag to pan.
• Shift/Control click to zoom.
• Double click to place a pixel.

Touch controls:

• Drag to pan
• Pinch to zoom.
• Double tap to place a pixel.

You can see it in action at http://8192px.co, the server is a droplet hosted over at DigitalOcean.

The server is written in Node with the only dependencies being mime and ws. Due to the lack of a good image library for node, it pipes bitmap data through convert, which needs to be available on the server.

The client has no external dependencies, and should run fine in any reasonable modern browser.

8192px's Issues

Sending a packet with bytes 4 or 6 set to 0 causes client to crash

At line 107 of the server file, there is no check for whether width and height are 1 and not 0. If they are set to 0 by a modified client or script, a DOMException occurs on the client and crashes the canvas when the resulting packet is broadcast, necessitating a refresh.

Site seems to be down

Chrome leaves the user with this error when trying to reach the website linked in the readme:
This site can’t be reached
8192px.co’s server IP address could not be found.
Search Google for 8192px co <-- link to google search
ERR_NAME_NOT_RESOLVED

title of readme is 8196 instead of 8192

Zooming is a bit trippy

I find that zooming either zooms in a whole lot, or it sometimes zooms out so far you can't even see where the actual canvas is anymore. Could this be fixed? It's kind of annoying trying to find the canvas after zooming out.

Make the moderators able to ban users

Only asking this because Mungo won't stop whining about it.

Recently colored pixels are flashing?

These unusually light squares keep flashing between light and normal. Is there any way you can fix this? These squares were all recently placed.

About the hints.

One of the links in the hints is to https://www.reddit.com/8192px [sic] when it should be https://www.reddit.com/r/8192px. Also, you should swap the words colors and change, or add an apostrophe to palettes.
