Customize your 4D Desktop
There is a SGUG user Jenna64bit who has contributed a ton of interesting ports, configs and tools for the Modern IRIX Desktop. She has collected and published her configurations on a GH page: https://github.com/Jenna64bit/irix-dotfiles
It’s worth visiting if you have a fancy for customizing that classic IRIX 4D Desktop. The page has the configs, plus links to her port of Barrier (control IRIX mouse and keyboard from your Mac) backdrops and more.
