Here's one I don't know how to use - scriptable data visualizations.

AVS SuperScope Visualization:

Here's a vertical scope.

Here's the parameters for a 2d spiral.

			[1] = {
				name = "Spiral",
				init = [[
				frame = [[
				beat = [[
				point = [[
d=i+v*0.2; r=t+i*PI*200; x=cos(r)*d; y=sin(r)*d				
				width = 24,
				height = 24,
				pixel = 4,
				drawLayer = "UIParent",
				points = {{"CENTER", "UIParent", "CENTER", 0, -100}},
				enabled = false

Here's some documentation regarding super scopes.


You can specify expressions that run on Init, Frame, and on Beat.
'n' specifies the number of points to render (set this in Init, Beat, or Frame).

For the 'Per Point' expression (which happens 'n' times per frame), use:
'x' and 'y' are the coordinates to draw to (-1..1)
'i' is the position of the scope (0..1)
'v' is the value at that point (-1..1).
'b' is 1 if beat, 0 if not.
'red', 'green' and 'blue' are all (0..1) and can be modified
'linesize' can be set from 1.0 to 255.0
'skip' can be set to >0 to skip drawing the current item
'drawmode' can be set to > 0 for lines, <= 0 for points
'w' and 'h' are the width and height of the screen, in pixels.

Image widget:

The idea here is you're given an entire framebuffer to drawn on with your Lua script. That's the image widget.

PNM ascii format images:
