DOWNLOAD OUR LOGO(S) The logo of Platform21 is a small platform in itself. It will change in style, colour and pattern according to its purpose, the season or Platform21's programme. Its creator, graphic designer Roelof Mulder, foresees that the Platform21 logo will become more than just a corporate image. He imagines a fashion label, a 3-D product design, a cookie, a sculpture. Watch this page to follow the changing moods of our logo and download your favourites. The first edition is called 'Once Upon a Time'.
