Often times we can see beautiful designs which overwhelm us, which don’t really have any practicality or are not usable at all. At the same time we can often see practical and useful designs being ugly and really not pleasing to the human eye. Let me show you some examples:
Disco Truck? What do discos and cement-trucks have in common? Looks cool though.
Sushi Chairs….Okay they have the usability of a chair, I’ll give them that but the design man, it doesn’t add anything.
There are many other examples like this which we can see in our everyday life. A really good one is USB Sticks. I always have a problem with USB sticks, I try to put the stick into the port, doesn’t go in, okay, let’s try the other side, doesn’t go in again, wait what? I try the first side again, IT WORKS, how? magic! Jokes aside, USB sticks are just very weird, at least for me.
A design I really really like is Water Taps with sensors. They just save so much time, are much more hygienic and much better for the environment. Triple the benefit!!
Cars! Cars are a thing I love. As a young person that is transitioning from a teenager to a young man in his twenties, everyday I get more and more interested into cars. Let me show you my favorite design in a car. It offers amazing design and at the same time, it is one of the most aerodynamic cars in the world. 
Say hi to the McLaren Speedtail. The speedtail is a perfect example of what happens when we combine beauty and usability (and a lot of money).
All in all, as the heading says, the best combination of beauty and usability (usually when they’re both balanced) will result in something we like to call “Good Design”.
