Torley head copy personal branding brand social media blahblah mosaic
Made with MacOSaiX, which is one of the easiest mosaic apps I've come across yet. It's pretty delightful to use: just select an original image and then source(s) for tiles. In this case, I specified a Flickr search for "torley" pictures, appropriately enough. But you could do just about anything.
It's also a nice usage of my Mac Pro's extra cores, since I can have it run in the background while I'm doing other things. I left this one on for about 2 hrs. to process. There's a "Mosaic Quality" indicator, and generally above 70% is good. It was taking a long time before it finally climbed to 73%. So be it.
