The spreadsheet mentioned is hands-down the most exciting program I've run into in recent months. They've built a usable, reliable, powerful system around a novel concept. The whole thing just works. Looking at the program, you wouldn't guess it's only 30,000 lines of application code. They've obviously made all their code count, kept it short and maintainable. 110,000 lines of test code is a small price to pay. [OK. correlation != causation, they might have made an even better program with less test code. Intuitively, I doubt it]
