Urbit [1] is a real software effort that many have considered a deliberate performance art.

Beautiful Code [2] is a well-known book that attempts to examine the development of some successful software projects from the perspective of the lead developers, and how they came to design decisions.

Beautiful Architecture [3] is a similar book focusing on large-scale project design.

This is a good book, though a few years old now: Beautiful Architecture: Leading Thinkers Reveal the Hidden Beauty in Software Design (http://shop.oreilly.com/product/9780596517984.do) Disclaimer: I'm the lead developer for one of the featured projects (though wasn't at the time).

I suggest Beautiful Architecture from O'Reilly.

It's similar to Beautiful Code (also mentioned here) with various chapters on different, independent topics: e.g. Facebook's data-centric architecture, Xen hypervisor, etc.
