In grad school, I took a ceramics class and was amazed how good it felt to be able to hold something I created in my hands (unlike a computer program). Since then, I've continued (with some gaps) to work with the medium and learn from real artists.
On Groundhog Day in 2011, the Chicago area was hit by 22" of snow, and I was hit by an idea: shouldn't I be able to do something with all of this stuff besides shoveling it? That's when my igloo obsession began. Ironically it has led to much more shoveling -- I usually have to collect snow off of my lawn. And 2016's winter brought nowhere near enough white stuff to do anything at all with. But have been able to create some nice specimens, including one that I slept in when it was -18F outside, and another one big enough for a party with 8 people inside.
