Groan is a simple Winforms tool to assist in visualizing random noise, using different approaches.

Initially Perlin noise is supported.

App design uses a Passive view approach, where the view has little to no logic in (where it can't be easily tested).

Most of the work will be found in Presenter components, which can mock dependencies as required for testing.

"change/selected" type events are only triggered when the user interacts with controls on the form and are disabled when the Presenter changes values to avoid triggering endless event cascades. (i.e. user updates a slider, which also updates a textbox showing the sliders value, this triggers the textbox change event, which updates the slider value, repeat...).

Uses .NET Dependency Injection package to implement IoC.
