Use the grey canvas on the left to draw a shape with the mouse while you hold down the left mouse button.

As you draw, messages containing information about the X & Y coordinates of the mouse will be published to a Kinesis stream. A Lambda function bound to the Kinesis stream will read the messages off the stream, perform a geometric transform on them, and then publish them to an SQS queue. The SQS messages will be received by the browser and rendered on the right-hand canvas.

There will be some latency between the send and receive times of messages between the left and right canvases. This information will be shown in the statistics panels.
