Look at the company you work for. They probably do lots of things in archaic or inefficient ways. Hack something together that makes things easier, and then get your managers and co-workers using it so you can get feedback and make changes. Eventually you'll have a product that you might be able to sell.

Even better if you can solve a problem that is industry-wide instead of company-specific. That gives you a bigger market for whatever you come up with.

Just be cautious of any IP restrictions in your contract! Otherwise they may claim your code or sue you into oblivion!
