I was feeling inspired by Apple featuring "Thirty years of Macintosh" today on the main website at www.apple.com/30-years and made some new wallpapers for my new 27" iMac when it arrives next week (hopefully). My first Mac was a Macintosh Colour Classic 4/40 purchased in 1993 that came with ClarisWorks and PC Exchange. I used that Mac everyday throughout high school. Read more about my Mac history here.
The wallpapers are 2560x1440px in size, perfect for the 27" iMac or LED Thunderbolt display. They were created in Adobe Illustrator and grain texture added in Adobe Photoshop.
