Sorry to highjack this thread but I thought I would show you guys some of the stuff I have found recently.
A note on spalting: Spalting is a result of decay it is actually very bad for you to breath the dust from spalted wood. It can cause respiratory infections, even give you lesions in your lungs, so wear a dusk mask.
From top left to right is spalted maple, maple burl, spalted poplar, root white ash burl, and on the bottom is some very weird maple. I dont know what was wrong with this tree but it sure looks cool. the very bottom is from the outside under the bark and the other pic is what it looks like inside.
