Iris is a Mac photo-library manager, but its latest release does two delightfully contrary things: a “Show Faces in Dock” setting lets you pin any person from your library as a real Dock icon sitting among your apps, and it escapes macOS Tahoe’s mandatory squircle icon shape with a legacy-icon trick only possible outside the Mac App Store. It’s the rare app that treats the Dock and the icon grid as places to play rather than obey. Flagged by Daring Fireball via developer Tyler Hall’s blog.
