After reading the user manual of my Canon Digital Ixus 30 last week, I learned a couple more tricks especially on the manual settings. The shot below was done in manual with some low exposures and high ISO settings. Despite the very dusty surface of the office glass walls, I was able to get past it and focus on the lights behind the clouds.
