a look at how creativity has evolved would be kool i think, though it would be boarder-line "history"... like the judging formats of contests through the years. how:
1.) it first started out as a pre-script given to the judges that had to be followed to the "T" or no points were awarded if you missed 180 degrees of rotation or missed a grab, etc.
2.) then moved to doing whatever you like and was awarded points for technicality/ difficulty alone,
3.) to the inclusion of rails,
4.)then lastly to the modern day where style makes up for a big portion, and how a BIG, stalled out 180 now equals more points than a wake-to-wake 180. there is an older article somewhere about the format in more detail somewhere for reference...
even free-riding and general riding has kind of followed this line of creativity evolve-ment above (or similar to it rather, and faster in progression).
you could mention specific individuals such as Scott Byerly and how he, because of his style and creativity is the "God Father" of wake, or Randall Harris or...
winches have opened up a whole new legit avenue for creativity, the ShredTown crew is a good example of that.
even writing about board graphics (and the artists) specifically (maybe too narrowed a topic?), but hey, if you want to mention the art on boards, there is some info here
