I used to have the link in my old email but don't anymore so I can't help you there, but if you have an iPhone, I highly rec the app ASL Baby Signs (or something like that). It has a list of words and you click the one you want and it plays a short video showing you how to make the sign. It's a little pricey ($5 I think) but totally worth it!! L has been doing awesome with his signs, and just yesterday he heard windchimes and looked right at me and signed "music" for the first time! So amazing...
