This has to be a designers worst nightmare. Quark, known for being hip on design and whatnot, unveiled their new logo earlier this month. Unfortunately, it bears a striking resemblance to the logo for the Scottish Arts Council.
Not only that, but at a discussion at Veer, a member points out how the logo is similar to an array of logos, most notably, this one and Veer's wallpaper.
All I know is that I'm glad I use Adobe products. Long live InDesign!
