Building an artificial sun that looks realistic [video]
In a sci-fi future where people are making long journeys on spaceships I can imagine rooms decked out with these to mimic a natural day/night cycle and outdoor spaces.<p>I remember first seeing lights like these a couple years back before from CoeLux (<a href="https://www.coelux.com" rel="nofollow">https://www.coelux.com</a>), iirc theirs are very expensive though. Awesome that this guy managed to DIY one!
