Build with Chrome - LEGO + Chrome = Awesome

I am a huge fan of LEGO and cannot get enough of it even as an adult. This virtual LEGO builder is so simple that it can get addicting. Your kids (age 4+) can have as many pieces as they need, change color at will and even hear a clicking sound when they attach them. If they don't like using the mouse, they can use their fingertips on a touch screen too. More importantly, there are no loose LEGOs to step on; so it will save you some real pain.
