Thanks. Yes I did. I put my username where the serial number should go to fill up some space. Since the forum redesign with the circular avatars happened around the same time that my Apple Watch arrived and the iOS 9 beta was unveiled, I was inspired to mash it all together. I briefly tried one with the El Cap background but it didn't look as good.
iOS style blurs are pretty easy to do in Photoshop. Take a copy of your layer and put a mask on it of whatever shape you want. Then run Blur Gallery > Field Blur on it with a radius of around 50px. Then put a brightness/contrast adjustment layer with a clipping mask on top of that layer. Lower the contrast around 20% and then adjust the brightness until it looks about right.
Well that's quite cool. You did a fantastic job.
It also appears that you know Photoshop as well as I know Sony Vegas Pro, nice!
