What about designing and building useful web apps or utilities?

Then provisioning and maintaining any popular sites would be your job.

You'd build an impressive portfolio and have a bunch of assets that you could sell or charge for if you ever wanted to.

Inventing something that didn't exist before and helping it to gain popularity can be pretty exciting as you see the progress over a longer term as opposed to building a site and handing it over once it's done.
