Joy of the Day 8/365: Sample Stitch.
Sample Stitch is a website that preloads the samples for three popular hip-hop songs (Jay-Z's "Otis," J Dilla's "Don't Cry" and 9th Wonder's "Impressknowssoul!!!!") and lets you recreate them through the computer keyboard. The effort makes it clear that a song made of samples can be as complicated to play as one that involves the keys of a piano or the strings of a guitar.
Why was this so engrossing? I'll explain it in more depth in a day or two. But for now, I'll just say that this made me happy today.
