Things That Should Exist (But Don't)

I'm no engineer (confer my brother for that), but there are some inventions that I think should exist and are (almost) within our capabilities to produce.

• A TV that shows different channels to each person watching it 
• Think about it. How many times have you wanted to share the same cozy space with a loved one/roommate/significant other, but disagreed over whether the Knicks game should have priority over Scandal?! (Hint: the answer is always the latter). How helpful would it be to share, conflict-free, the one flat screen surround-sound TV in your house (because who has more than one?!)

• Windshield wipers for your glasses
• OK, I know this idea is totally dorky, but for all you spectacled folk (which is everyone by now, seeing as it is "cool" to wear fake glasses too), you know the suffering that follows getting caught in the rain, resulting in total loss of vision. I can't tell you how many times I've wanted to pull a Hermione and Impervius my glasses.
