Planar Slider UI Component
Planar Slider UI Component is an underused UI component that provides twice the output compared to a traditional track slider. I detail its strengths and weaknesses in the article Considering the Underused Planar Slider Component in User Interfaces.
The below button launches a small sample application called Planet Gen that leverages planar sliders in the UI. Improvements to the planar sliders in terms of x-axis and y-axis labeling in addition to value/range labels would be beneficial. The sample app is just a basic interactive demonstration.
