Elon Musk rolled up to a Tesla press event yesterday in an electric semi truck, unveiling his latest project to the world. The semi has been hotly anticipated since Musk first hinted at it last winter, and he's been hyping it up on Twitter this week, promising that the reveal would "blow your mind clear out of your skull and into an alternate dimension".

It's part art, part science - but considering we know virtually nothing about extraterrestrials, should we really be calling attention to ourselves?
