This looks absolutely gorgeous. All the applications I tested, even crappy ones like Skype, look perfect. Absolutely fantastic job, thanks!

Is this theme same as the "Numix - GTK3 Dark Theme" from Ubuntu Software Center?

I didn't know you're trying to make a job out of this...
me4oslav Featured By Owner Aug 15, 2014  Professional Interface Designer
Well now you do. ;)
But if I wasn't it is still a product which we (Numix team ) made so we are free to charge for it if we want to, especially considering we give all our basic stuff fore free.

I have no coins, would you share this for free?

I'm 99.9% sure you are using a Linux distro you got for free.

So what do you say? I'd really like to use this theme, if it works ok on my box.

I hope you'll please share in the good Spirit of OpenSource...

I have actually donated 20 bucks to the distro I use (I use Ubuntu). ;)
Now, the reason I can't give you this away for free is simple - all the other users have paid fr it, it would be unfair to them if I give it away to you for free. Double standard is something we can not afford to have.
P.S. Open Source and freebies are cool and everything, but remember - we (people that create software and designs and everything) are still human and we need to eat and pay bills and stuff, so we need money like every other person and Numix happens to be my fulltime job for now and I don't wanna be left starving by giving paid stuff we've worked upon for free. That would be really bad.
