Avatar Permalinks

[itsthatguy]

Once we're actually generating avatars procedurally, we can provide a permalink to an avatar's given attributes. That way, if we add more attributes in the future and the mapping changes, people can still use the same avatar.

What if we base64 encode what's returned from Potato#parts and use that as the URI token?

var encoded = new Buffer(JSON.stringify({data: 'foo'})).toString('base64');
// 'eyJkYXRhIjoiZm9vIn0='
var decoded = JSON.parse(new Buffer(encoded, 'base64')).toString('ascii');
// { data: 'foo' }

If you're cool with that, then we just need to figure out what the route should be. @bigtiger had the suggestion of throwing the new avatars under v2/, so that the existing avatars truly never change.

Oh, good idea. We could also make a change to how we deliver the images.

Scenario

1. 'key' = Base64 encode the route input string
2. check for existing image with name that maps to key
3. if image exists -> return image
4. if image does not exist -> alrogithmize string to generate new image with name key

Summary

This would allow us to save images for the long haul.
