Imagine photos that are always sharp. Imagine camera that doesn't need to focus on the target, because images can be re-focused as you are watching them. Now imagine that it's real - and its name is Lytro.
Lytro is an innovative digital camera that captures "light field" instead of traditional pictures. Light field cannot be captured by standard cameras; it requires special type of sensor - "light field sensor".
Im my career I've seen a few projects that was "overengineered". Talented developers and architects designed complex architecture and used fancy solutions to achieve goals, which could be otherwise achieved much easier. This situation is quite common in various projects across the globe, from software projects to car industry to drugs research.
People usually think with "patterns". It's partly due to our system of education, where small children are teached that for each problem there is only one correct solution - the one on the back of your book ;). This education system limits our divergent thinking, which is essential for innovative thinking.
