I'm working on a very basic runtime script interpreter, here you can try it out a little.

To load a couple samples, use the dropdown in the topleft to select 'samples' then click the 1-5 buttons (only 3 in this build).

If you make a script and would like to save it, use the same dropdown to select 'Save' and then click a number button to save it to that slot.  The 'Load' function will load it back from that slot number later. 

Copy and paste with WebGL is a bit of a struggle, for now there is a small clipboard icon button you can use to help with this.
