Tixelated

Like Kickstarter for baller house parties (and not just that one dance scene where Chris "Play" Martin had a blatant erection), Tixelated not only functions as an event planning/invitation platform, but also (and more importantly) aggressively encourages people to pitch in for booze, food, headlining rock bands, and mini dancing donkeys via PayPal so you can "party harder".
