I love to go hiking and occasionally even go on some back packing trips. I have some pictures from some of the more recent back packing trips that my friends took with their digital cameras.
I have also written some emacs-lisp extensions. They are a great way of postponing real work. Some of it has even made it into Emacs proper!
I also do a bit of photography and build stuff with Lego. These days I can't seem to find the time to do much of these.
