+## Extras
+A bunch of simpler examples exist:
+
+- [`bezier_tool`](bezier_tool), a Paint-like tool for drawing Bezier curves using [`lyon`].
+- [`counter`](counter), the classic counter example explained in the [`README`](../README.md).
+- [`custom_widget`](custom_widget), a demonstration of how to build a custom widget that draws a circle.
+- [`events`](events), a log of native events displayed using a conditional `Subscription`.
+- [`geometry`](geometry), a custom widget showcasing how to draw geometry with the `Mesh2D` primitive in [`iced_wgpu`](../wgpu).
+- [`progress_bar`](progress_bar), a simple progress bar that can be filled by using a slider.
+- [`stopwatch`](stopwatch), a watch with start/stop and reset buttons showcasing how to listen to time.
+- [`svg`](svg), an application that renders the [Ghostscript Tiger] by leveraging the `Svg` widget.
+
+All of them are packaged in their own crate and, therefore, can be run using `cargo`:
+```
+cargo run --package <example>
+```
