Today's the day, Tesla (TSLA) junkies. 

On Sunday, Elon Musk tweeted that the Tesla semi truck will be unveiled on 8 p.m. Thursday. He went on to claim that the vehicle "will blow your mind clear out of your skull."

Very little is known about the vehicle, although a Reddit user in California posted a photo of what could be the initial testing of the truck. The truck didn't have a Tesla logo or anything that would confirm the speculation. However, it does look a lot like the teaser photo that was released by the company.
