David Lublin from the Vidvox crew released an awesome new toy this week - the GifToSyphon app is a cool Giphy powered and Syphon-backed animated gif player! So yes, you can search for gifs and instantly play them in CoGe and every other Syphon supported apps, but the app also downloads the gif files so you can play them even offline!
Download GifToSyphon (requires Mac OS X 10.9.5 or later) More info: http://vdmx.vidvox.net/blog/giftosyphon
