But bringing this to Bat Signal levels is harder than it may seem. The Hacksmith Industries guys show this via a small-scale model using a flashlight. You also have to place a convex lens a specific distance away from the image to make it visible and in-focus on your final surface - and flip the image upside-down to account for refraction. But even that isn't enough to project a clear image in the night sky. To make an image appear on a surface, you need to put a cut-out of that image in front of a light source. That's mostly because the light needs to hit something to actually project an image and because light, in general, is finicky. Getting a projector-like light to beam up into the clouds isn't as easy as the comics or movies make it appear. In a YouTube video documenting the project, James Hobson of Hacksmith Industries clarifies that a functioning Bat Signal is largely a thing of farce. But leave it to the guys behind the ultra-popular YouTube channel Hacksmith Industries to create a functioning Bat Signal that outdoes the 'real' thing. While you may think creating a real Bat Signal is as simple as shooting a gigantic beam of light into the night sky, it's actually much more complicated than that. Though Batman may be fictional, his Bat Signal doesn't have to be, thanks to some high-level engineering and serious problem solving. They aren't cool enough for our buddy Bruce.) Without it, how would he be summoned to handle anything amiss? (Forget cell phones. Face it: Batman is nothing without his famous Bat Signal.
