Signature rep block generator

Tonight I wrote a Python web script that will generate bars to indicate rep scores. E.g.

It's flexible, in that it only shows the reps you ask for, and in the order you ask for them. It doesn't keep track of your rep scores for you, but we were already on the honour system for that anyway.

If you ask for a rep it doesn't know about, you'll just get a black background. E.g.

To use it, just create an image tag pointing to

E.g. http://alfedenzia.com/eprep/?i=2&e=5&r=2554&g=2&f=1&c=2&@=1&x=2
