Now this is a DIY project worth investing your time in. Coffee tables are typically dull, but are very useful as a place to hold your beverages as well as use as footrest from time to time. What if you could have the best of both worlds? Instead of having the usual dull coffee table, make yourself a pinball machine stashed inside of a coffee table. Never again will you be stuck watching commercials with that bored expression on your face, now you can pass the time with a few rounds of pinball.
