In fact, it takes a lot of effort to create a completely user-friendly, intuitive & efficient web interface...
There's definitely a great amount of unorthodox UI solutions that can be found today. Especially with thousands of SAAS websites and thousands of interactively designed blogs, e-stores online... We've researched just a few of those and here's what we found out about top 5 UIs. All of which were recently implemented by the big web players.
We tried to examine as many examples as possible and we found a profound evidence of a pattern. An evidence that a majority of big web players is NOT afraid to approach UI design with unorthodox, fun and engaging solutions. So, the list starts with a great Interaction on MailChimp's website. The way they make sending a first email marketing campaign a fun and engaging experience (as it is indeed) - is remarkable. Great way of playing it cool with your audience.
Web interfaces of all kinds came a long way since their first years in the 1990s. In fact, the difference in 2010 & 2017 UI/UX is just as drastic... Brian Williamson
Another example of taking an ordinary User Interface detail and turning it into a marvelous experience for a website visitor! This one was found inside a UI of the Slack messenger service. It's available both as a web version and a separate, cross-OS application. The nice touch is that when you enter a HEX color code there (e.g. #ff3333) - the messenger will display it for you instantly in a separate little box.
This is a small detail, still feels like an extra mile that the service is willing to go to make life easier for its users. Did you know, that Google Maps have a little easter egg UX feature about the shadows? If you're looking at any building or a landmark on Google Maps - the service will display shadow it casts. In real time! All accordingly to a time of the day.
