I'm always looking for more ways to find GIF's and share them quickly. Enter GiF for Mac by Riffsy. GiF for Mac is a GIF search engine that sits in your menu bar and allows you to search for any GIFS. You can then share them directly from the app and even drag and drop them into apps such as iMessage. More impressive is the GIF saving feature which allows you to save your own GIFS directly into the app for future use.
GiF for Mac can be downloaded for free from the Riffsy site.
