I am a huge fan of taxidermy, and have a couple minimal pieces already. I've delved very minimally into it myself (I once skinned a pair of antlers with a skull plate still attached) and would like to do more if I could ever handle it. I would love to try bone articulation more seriously, and am currently working on an exploded rodent skull.
A two-headed duckling is on my taxidermy wish list. I would be most pleased if it had two heads naturally by a birth defect, but a skillfully modified piece would be fine too.
This is the type of piece I aspire to do myself some day, it is so hauntingly beautiful.
