There have been a number of questions in past months about using the canvas. Unfortunately there’s a learning curve with using the canvas since it’s unlike other components in how you work with it. I had some time, so worked up an app that should help others over that learning curve. It doesn’t show everything you can do with a canvas, but should get complete newcomers started and productive.
Here’s the live version: https://canvas-examples.anvil.app/
And the clone version: Anvil | Login
Nice, thank you 
Here’s a little snake game that may be useful for someone to see:

‘ijkl’ keys can also be used to control snake movement.
Awesome job! Thanks for sharing
@jshaffstall - thanks for sharing this post. the app you wrote to explain how canvas works in anvil was very easy to follow and well laid out - excellent job!
Thanks @jshaffstall this is excellent timing.
