ClapHD

What the picture shows

A pair of light-skinned human hands pressed together palm-to-palm in a clapping or prayer gesture against a plain white background, rendered in a slightly blurry, low-resolution photographic style. Chatters most likely use it to show applause, congratulations, or enthusiastic approval of something in the stream.
