EVERYTHING SYNTH
via The B-Roll "Since I need to come up with some screen-printing designs for our little burgeoning artist collective I decided to google image search “vintage control panels” for inspiration. I ultimately want to use these components to create an imaginary 1950′s modular synth. Some kind of modular that never existed but you wish it did. I made these in Inkscape but they were most definitely not freehand. I actually didn’t use the tablet at all. It was created using a lot of primitive shapes and the union command. I really dig the way they look though."
