+# ImgSyn Image Synthesizer
+
+ImgSyn is an image synthesizer written in rust, capable
+of applying layered effects and transformations to a canvas
+to produce an image. The image can then be given out as a PNG,
+or accessed from rust directly.
+
+Notably, ImgSyn uses the same model as rust iterators, just for
+images.
+
+![A graph created in ImgSyn](./graph.png)
+
+See the tests in lib.rs for some examples.
