You're just asking for a lawsuit from Google. If I owned this domain, I would delete it from my portfolio. Why build a website on something that will cause you to go to court, pay lawyers' fees, end up losing the domain you built your website on, AND being fined upwards of $10,000? There are better, safer options for any project you want to build. And the people who are unwise enough to buy Googly from you will probably lack much of a budget anyway.
You could get away with avoiding a trademark lawsuit by developing the domain in a way that clearly does not infringe on any of Google's property. However, the domain itself is worthless so I agree with ImageAuthors - drop the domain and move on to fresher pastures.
