Ideas don't always come as easy, I find putting pen to paper or hand to mouse and letting your mind roam free is a great way to get ideas flowing. Experimenting and not trying too hard to get the finished product can give you just as many good ideas. I try to be different in my approaches to see what I come up with. Of course it might not always work out as expected but the next doodle or sketch might be the idea that is worth pursuing.
Cells
Up close human cells can be beautiful and inspiring, they almost look like things from another world.
