This is an annual collective that ran for i believe 4 years, from 2013 – 2016 of creative interpretations by animators and animation companies of the traditional holiday Yule log. It was started by designer/animator Daniel Savage and has grown to require a panel of jurors to narrow down a thousand entries to the 50 best. Love this as a resource to find talent, styles, and just for the pure, open spirit of the thing. Looks like the website has retired but you can still see a compilation here. Thanks Dan!
