Since 1980, the Celtic Media Festival has brought together people who broadcast, and now Webcast, in Celtic languages. Videoblog Gwagenn.TV provides a report (with autoplaying video) from the 2009 festival whose clips and interviews are spoken and subtitled variously in Breton, French, English, Welsh, Scots Gaelic and Irish, Catalan, and Basque, not all of which are actually Celtic.

The Essence of Line is a collection of over 900 drawings by French artists "from Ingres to Degas" by the Baltimore Museum of Art. I'd link to some highlights but the site did such a stellar job of it that I'll just direct you there. They also have some sketchbooks. Note that some of the drawings have short essays about them. As a related link, here is the famous Demonographia, with drawings of demons by Louis Breton and descriptions by Collin de Plancy.
