I went with Viral Craft Fair and created 2 different posters on the computer. Yesterday and today I've been debating between the two. One is a single button that I transformed into a virus germ and the other is a more repetitious poster with a lot of germs and I added buttons within the germs.
After sleeping on it, I think I'm going to go with the more repetitious one I created because it's more visually interesting and "virus" comes off better. Also, you see it and want to get closer to see what the germs are and wonder why there are buttons.
