David Siegl is an artist who has (since 2002) sometimes done work that appeals to the furry fandom, although the majority of his work over the last 30 years is in the realm of science fiction, fantasy and horror. An example of his anthropomorphic work is the mini-comic Predator and Prey available in Katmandu #33, due out on 31 January 2006.
David often posts artwork for various online communities - some under his real name, some under the nickname Tzaoec, and some under other names. He is most active on Yahoo! groups such as skunkworksAMA, rebacca_forever, robinhoodadult, zigzagsroom (which is naturally about Zig Zag), sawyercatunleashed and wildlifersx.
