In some way or another, I've been taking music and video from my computer and playing it on my TV for years, and it's always been awkward, ungainly, and unreliable. But these days, when I want to do that, my mental image is this: A video plays on my phone. I look down. I wrap my fist around the video. While the video struggles against my palm, cats meowing or singers cavorting, I wind up like a pitcher and heave it at my TV. It flies through the air in bits, like that Wonkavision scene in Willy Wonka and the Chocolate Factory, before slamming into the TV and reassembling itself, large and cinematic.
