One of my favorite books as well. Every time I've gotten to the ending (especially the part where they discover the massive sculpture through trillions of universes) my mind is blown and I end up sitting and thinking about it for hours. I have a similar reaction to Egan's Permutation City when the couple living in the simulation adjust the clock rate so the computer running them only executes one clock tick every second, every day, every year, every million years, every billion years, every trillion years, etc. Puts me in a contemplative mood.
