A word cloud has multiple possibilities in the business world. Despite the obvious Marketing and Advertising options, flyers, billboards, brochures, etc... What a unique business card could a person have with one of these. Not to mention using a word cloud to display the company's Mission Statement. I think making a Word Cloud with all the employee's names would be really neat as you walk in the door. Think about how attention grabbing that could be. Listing all of your services or products would also be unique. To be honest, the possibilities are endless with what all you could do with these with each being more creative then the first.
