I'm very sad to hear about the death of Charley Harper (via The Skinny). It's easy to sum him up, as a wildlife illustrator with a very distinctive, geometric style but that doesn't really do him justice. I heard about him via the illustrator Bill Wray who applied his style to Dexter's Laboratory. I saw it and was hooked. He does for wildlife what M Sasek did for travel. I was lucky enough to get one of his exhibition posters which hangs in my living room (behind the old movie lights in this photo). I enjoy it every single day. It's got lots of things that I like - ladybirds and primary colours and geometry and white space. I think it's perfect. So I am genuinely sorry to hear about his passing, but glad that in times like this the web rallies together.
