Adobe App Icons
Project description, posted in 2012:
I've been using Adobe's Creative Suite software for a while, and decided to design my own take on the now-standard "Periodic Elements"-style CS application icons. While I did recently gain some interesting perspective and appreciation for the thinking behind the most recent iteration (CS 6) from Adobe's design team, I still wanted something more nuanced and multi-dimensional than the official icons. I hope you enjoy them!
The icons are free to download, and are available in ICNS format for Macs, and ICO format for Windows PCs.
The Mac ICNS files are HiDPI resolution, which means they're optimized to look great on all screens, including Mac Retina Displays!
