Oh, what a fun exercise! Image generators are nothing new for me, but I love to discover new ones. While at first glance they may just seem like playthings, they can be very useful when creating web content. I've created many websites over the years and took advantage of free online button generators.
I receive the RSS feed to The Generator Blog and love to play with new items as they are announced. I encourage you to explore the fun and useful generators. Here is one I created back in January with the M&M Character Generator. Don't you think that the likeness is remarkable? :)
