Yesterday my coworker laid the DropMix board out on a table and started dropping cards. Immediately catchy music played from her phone's speaker and three passing coworkers stopped dead in their tracks. As she removed a card and added another the music changed to accomodate the new beat and one person said "is that, like, a mixing game?" Then another spied the colourful box the DropMix resides in when you want to shove it in the closet or under a bed. "Harmonix? The Rock Band guys?" The final never took their eyes off the board as she replaced another card and the music changed again. "I want to buy this."
