CoreMidi/OSC support

I also don't have coremidi experience, but I heard Jack has an easy API, handling both audio and midi (http://jackaudio.org/).

Things you could do using http.get?

You can also use it with the google chart API: function setup() spriteMode(CORNER) grImg=nil local tbl={["method"]="POST", ["data"]="chs=320x400&cht=p&chd=t:32.787,50.82,100,42.623&…

The example also uses my zoom3D library. --# Zoom3D -- Zoom3D library v1.1 -- Herwig Van Marck -- usage: --[[ function setup() -- zoom3d=Zoom3D(20,30,vec3(0,0,0)) end function touched(touch) zoom3d:touched(touch) end function draw() …

SphereQuest!

You can easily implement a basic lighting by multiplying the color with the cosine of the angle between a light direction and the normal in a vertex. Add some ambient light and voila... --# Main -- 3D example -- Use this function to perform your …

triangulate

@Simeon do you know if there is any progress on improving the triangulate function, returning indices as well?

saveProjectInfo() and saveProjectData()

Syntax highlighting? (for the creator or those who know!)

The Textastic app uses TextMate-compatible .tmbundle packages and .tmTheme files for syntax highlighting (and it supports objective C).

ScrollBox, a class for scrolling text

Isn't it that textSize should not exceed 2048 pixels (as I mentioned in my zoom library)?

Langton's Ant

Very nice! A couple of suggestions: - use noSmooth() before the sprite command - draw the board on the neighbouring screens as well (so you can pan and zoom on the corners of the screen as well) for i=-1,1 do for j=-1,1 do …

@Simeon do you mean custom sprite support or access to the photo library (or both)?

@Maxiking16 wouldn't it be better to put that in the class, rather than in a global variable?
