Ask HN: Where to find learning projects

Hey there,

some background information: I have a business information degree in Germany, working as a software developer for two years now.

99% of the time I only have to write simple scripts. I read every book about development, techniques, languages, you name it. I know I have a lot of knowledge, but there is nothing I can work on.

People always say "well, just commit to open source projects" which is easier said than done. And while this would be awesome, I want some kind of big picture to work on.

Question is: If you have no needs yourself and you are not so smart when it comes to "super cool ideas", how can I get some bigger projects to work on?

Edit: And yes, I am currently looking for another, more challenging job.
