I have found an icon on the web of Albert Einstein (attached). Einstein is of course an expert. I am in the process of constructing presentation slides where I need to differentiate between novices and experts in a simple, visual manner. My idea is to differentiate by the largeness/fuzziness of individual's hair!
So, I require the aforementioned icon to be duplicated and changed, so that at one extreme, the icon is bald, and at the other extreme, the icon has a very big/fuzzy hair-do. Ideally, I also wish to have eyes placed in the icons.
Alternatively, if you have better icons in mind, I am VERY willing to consider these. In fact, if you can create a smarter looking, funnier, design than the rather pale-looking icon attached, then that is obviously a big plus!
