I shared these with an art director/designer friend late last year and he loved them. If you are constantly using InDesign, Illustrator, Flash or Photoshop, they might come on handy for you too. And if they don’t I guess they’re just kinda cool to look at.
If you have one of the more recent versions of Mac’s Spaces (the ability to have different desktops), then you could definitely use all of them at once and or use a couple of them and still have room for personalized wallpapers. If you’re a beginner designer, use these as a learning tool too. Knowing tips, tricks, shortcuts or whatever you want to call them will definitely come in handy.
I’m not sure who actually created these, and I wish I could give them credit here. For all I know these are actually templates created by Adobe. If you’re any other type of designer or developer, I recommend checking [this] out for other really awesome wallpaper design tools.
