When I was a kid, one of my absolute favourite things to do on the PC was to mess around with a free virtual Felix - like the cat from the cat food adverts - who would roam around the Windows XP desktop, chasing balls of string between program windows and curling up to take a nap on the taskbar. I have no idea where the game came from - a dream, perhaps - but 30 years later, I still think about it as a perfectly formed way to lose hours on the PC without actually doing anything.
Virtual pet sim Weyrdlets is like Animal Crossing on your desktop, except you might get some real-life work done too
