Couple things about interfaces:
	Should it float?
	Should it be a separate window?

Frozen Fractals, and addition of buttons and frames

How about adding a select color button for the circle in our TKinter program?
	askcolor function returns a color
	from tkColorChooser import askcolor

OS tools:  You can use your OS toolkit for stuff
	The color chooser will *probably* be different on other platforms
	How about a different window manager?

Generally speaking, use OS stuff and resist custom tools
	They'll fit in with the user's color scheme, etc
	And the user is likely used to using them

Let's take a look at a different toolkit:  Dear ImGUI
	Example in the GUI I added to the vulkan tutorial
	State:  Something that must be remembered outside the GUI
