Decimen is an open-source web app that moves files between devices through an animated QR stream, requiring no direct network connection, pairing, account, or native app.

I remember when I learned how to transfer files from my IBM Thinkpad running Windows 98 to my Compaq iPaq pocket pc over the built in IR transmitters. It worked, albeit very slowly.
