LocalSend: Share files to nearby devices

I discovered this from a post on Daring Fireball and it was an instant download for me. I like Airdrop for sharing photos with friends and family, but that only works on Apple devices. LocalSend does the same (and more) between a wide variety of devices. Even if you need a way to send clipboards back and forth between devices LocalSend does that. And it is open-source and free to boot, with the option to give a tip.
