The cats sitting on a fence in early builds of Windows 8
I love whimsy and Easter eggs in our industry, and I add them whenever possible. There is always a reason to take them out (performance, potential user confusion, grumpy devs, whatever), but prioritizing them says a lot of good about the team and project.<p>In most cases, in my experience, I can tell what generation an engineer comes from based on attitude to whimsy. Younger devs almost always don't like them. Too much effort, too much potential for trouble. Older devs, especially past retirement, almost always like them. This industry started with a sense of humor and fun.
