The little bird was one of a series of free icon downloads. However, I think that one orginally had on a St. Patty's day vest and theme going for it. I undressed it;-) and I did make the little step and sign...and the cathe logo is the little one used when you see Cathe post on the menu of replies for a thread.
I sort of mess around with the paint program...it's like the old colorforms..if you're old enough to remember those...you just layer little images to make one.
