Last weekend, I created this Neumorphic UI for my own learning. Basically, this UI pattern is a combination of current flat UI and old skeuomorphic principles.

I am not sure about its performance on the web after implementation but yes it was a great experience working on it.
I hope to come up with more UI designs in this series. If you like it, don't forgot to press 'L'
