Water in a Bottle

Today I had another assignment (course) at university. This time about artificial intelligence and learning systems (intelligent products). After this first lecture, I caught myself staring at my water bottle... I like it how coloured shadows can be casted by sunlight shining through coloured glass or plastic.

This evening I had the most wonderful evening with my girlfriend. We just did some questionnaires for her study (psychology) and a game of rummikub.
