* You cannot see through the glasses, so I don't recommend walking around with them on.
* The individual keychains are not synced. I just practiced pressing the 'ON' buttons simultaneously.
Step 1: Materials
* Sunglasses (that you don't mind destroying)
* 2 digital picture frame keychains -
* Pliers (to remove the keychain from the picture frames)
* Paint (to cover the glue and blend the picture frames in with the glasses better)
* A computer (to download the images to the picture frames)
