This isn’t in the realm of projection mapping, but I’m sure some night soon this will be brightly displayed on the side of a building. For now I’m using this blog as a way to share the idea.
It only took $163.14 to make 3,000 4″x4″ stickers that 86% of them “disappeared” in less than a day. I have since updated the design to incorporate the hashtag #CatCallingIsHarassment to help others share the idea and uploaded the files for anyone to download, share, or printing. i.e. signs & stickers.
Initially someone printed 500 Vinyl stickers for free, they were amazing quality, but limited, more expensive, easier to remove (in one piece), and more detrimental to the environment. For paper stickers I found this company had good prices and turn around time, I’m going to see what else is out there, but for now: https://www.printplace.com/products/promotional-and-event-stickers
Hopefully you can take it from here, spread the word, et cetera. Let me know if you find a better printer.
