I first noticed designs featuring geometric angles in 2011 in Kuala Lumpur.
This Belgian geometric poster for the Triennale Brugge in 2015 reminds me a lot of the Malaysian poster, although I think the angles were provided by a reflective geometric structure in front of an older building.
Here’s some more: a 2015 Amsterdam Music Festival poster.
A 2012 calendar in Belgium.Yet another Belgian poster. This one I attempted to recreate, sort of, with clouds within and behind a geometric structure.
Of course, once something becomes popular someone goes and creates an app for that! I have been playing with two apps, both from Pixite, one called Matter and the other Fragment. This is some clouds as we were flying out of Puerto Vallarta run through Matter.
