How to: pixel icons

Hey all!
Have’nt been here for a while! Still cool.

I’m building a site which is graphically very technically orientated. I wish to build up a language of very simple and very clear pixel icons. These icons will serve as buttons and symbols relating to the content. They are going to be pretty widely used, so on a forum, newsletters, site etc.

I am wondering about the best practice for building these?
Sizes?
Optimisation?
Technique?

So, if anyone knows of good resources for tutorials, techniques etc. I would be really glad of your help.
I guess a good example of what I’m trying to achieve is here on this site! Small tight icons.

Any input as ever really appreciated.
Good to be back
