Thinking of a project

I want to do a project. I don't know what kind of project, but I would like to do something by my own.

I have some ideas, by example, a Web Based IDE, a Framework of something, some kind of killer app. But I need some boost.

I'm installing the tools first, I never care if they're not the correct tools. I want to take a road and see what happens. I think that real life is something like that. You only take ways, and try to get to some place, but along the way you can find more interesting things.
