Bold abstraction is the order of the day on this week's top flier design. The interlocking lines and squiggles on this bold, largely black and white flier come together to strongly suggest circuit boards, computer parts and other high-tech concerns. The big circle puts me in mind of a record -- obviously appropriate for a DJ night. And that bright-green splash of spot color works wonders against the otherwise monochromatic design, really helping the whole thing pop and catch the eye. We're told this Lipgloss flier by Gemma Bayly should be around and used for a while, and this week it gets our nod for flier of the week.
