A quick Google search for "word cloud generator" or "create word cloud" will produce varying results of free online word or tag cloud makers. I personally think the best of these is Wordle.net. Wordle allows you to quickly create a visual representation of keywords and their frequency. The below is one I generated from my own Curriculum Vitae or CV [PDF]:
Lusk, D. L., Evans, A. D., Jeffrey, T. R., Palmer, K. R., Wikstrom, C. S., & Doolittle, P. E. (in press). Multimedia learning and individual differences: mediating the effects of working memory capacity with segmentation. British Journal of Educational Technology.
An article having to do with multimedia learning (about segmentation and working memory capacity) that I am second author on has been accepted for the British Journal of Educational Technology! Not only that, but it was accepted without revisions!
How absolutely fantastic is that? It is beyond fantastic!
