Custom Taxonomies but with Icons associated?

Can I have custom taxonomies but with icons associated with them?

Example: I want a list of skills I used for my portfolio item (eg. PHP, MySQL, CSS etc).
Instead of text, I thought of displaying icons.

So I needto somehow set icons for my taxonomies.

How might I do it?
Is it very complex?
How might it look or whats it like to build it?
the steps?

I’d suggest the Taxonomy Images Plugin. It says it’s in Beta but I’ve used it on a few sites already and it works great.
