The Facebook Icons series from Leonard Savage is a unique play on the Facebook Like button and its thumbs-up graphic. The series features five different hand gestures accompanied by a corresponding comment that spins the "Like this" into various forms.
From the traditional two-fingered rock 'n' roll sign with the caption of "Rock This" to a complete palm up to symbolize "Stop This," Leonard Savage has created a unique series that would definitely appeal to the Facebook population.
Savage also puts a humorous play, with a finger and a green speck (which one could assume is a green booger) and the caption "Pick This." According to Leonard Savage's site, the concept for the Facebook Icons came "from some ironic meeting notes."
