I walk by it every week and I still stop every single time. I was born and live in the neighbourhood and I've seen it progress. It's really inspiring to see man can conceive such beauty and wonder. I agree with other comments mentioning we software developers can/should especially appreciate it for the humongous endeavour, work in progress and feat of engineering it means. I also like to think Gaudi and Barcelona have impacted the way I see and appreciate design, and how I lamely try to embed it into my work!
