For the most part, here at Hackaday we’re more interested in how something was made than the backstory on why an individual actually put it together. Frankly, it’s not really our business. But we’ve been around long enough to know that practicality isn’t always the driving force. Some folks build things because they want to challenge themselves, others because there’s nothing commercially available that quite meets their needs. Of course, there’s another camp that just builds things to look cool.
