1400 icons in 16 styles :/
The styles are stroke width from what I see?
In there defence - I am designer and it's sounds odd to me too, marketing, but there are people that don't have software to modify icons and these 16 variations with small difference between is great for them to use as png, svg and webfont on there site.
Check out Smashicons - they did a good job of doing marketing and icon styles. Bought their icon set immediately.
To me when someone says 22000 icons and then turns out its 1400 unique icons not only that the difference is in stroke width makes it very "fishy".
Yes, Smashicons are awesome. Totally agree.
Visually it's impressive, but from a usability POV it's really confusing.
I'll be short. This is one of the most confusing websites/webapps that I have ever used. I think three times before clicking anything :) Visited few pages and created acc and finally a list of icons in some normal look which is not rotated, cut inside box, etc. EDIT: I thought that back button in browser will help navigate the pages, took me to the home page several times... Top bar jump from the screen and attacked me when I hovered over user icon in top right. Ok, managed to get to free icons, I know which one is download icon but took me a while to get the other ones. Enough for now.
That is one insane icon set. And that site! Impressive.
