Twitch's next way of letting viewers interact with streams is with GIFs. The latest customization tool for the popular broadcasting service arrives via a partnership with Giphy, and the way it works sounds pretty simple. A broadcaster sets a location on the screen for where users can drop GIFs, and once a stream starts viewers click the Giphy icon to start searching for the perfect reaction to the 'caster's on-screen antics. From there, it'll overlay on the stream. Cool! Before you get any crazy ideas for trolling, GIFs will be curated for appropriateness.
