Your federal income tax forms are due today. If you haven't started and you need to file something harder than the 1040EZ, you may want to think about filing for an extension.
If you're done with taxes and want a diversion -- and you're old enought to remember the old Space Invaders computer game -- you might have fun playing a round or two of Tax Evaders, a game in which regular people try to destroy the tax breaks of large corporations.
The not too subtle point is that large corporations win. But it's interesting those in a nostalgia/retro sort of mindset.
