I didn’t realize how many different sounds our hands could make until I played with the American Heart Association’s Hands Symphony site. They are using the site to promote learning CPR, and in doing so came up with a rather viral campaign.
The Hands Symphony site has three different music genres (dance, hip-hop, and latin), and then each genre has 12 different sounds made using human hands. When you click on a set of hands that animation will begin looping into the sound you’re listening to, and even with all the sounds playing at the same time I found the beats it produced to be really good.
This isn’t something you’ll spend hours playing with, but it can be pretty cool to show people. It’s definitely worth checking out for the few minutes of entertainment it will provide.
