Whether you're a graphic artist, looking for a photo that matches your color scheme, or you're bored and trying to think of the most fun, least productive way to search the web for images, here's an interesting tool from the folks a 500px.
No typing is necessary, you draw the image you're looking for and the results are instantly displayed.
To be clear. This doesn't work at all. The search engine displays images that slightly resemble the color scheme you used, or generic pictures that might match the stick figure you drew, but that's about as close as it gets. If you're looking for pictures of Spongebob Square Pants to use in your next meme. You've come to the wrong place.
But it IS worth a few minutes of your boredom.
