I changed the amplitude slider to a direct manipulation handle since Apparatus makes it so easy.
Sliders = "change some number somewhere"
Direct manipulation = "change this thing in-context"
:)
Still gotta figure out how to convey affordances of arbitrary objects (both on-screen and off-screen), but we have lots of clues.

I added a mechanism where expressions can see the time since last frame (dt). This allows for consistently timed animations.To make a ticking time variable, just make it "followed by" time + dtI remade the first diagram from Circles Sines and Signals.Note that this would not be easy to do if you only had access to the current time because when you change the frequency the rotor would "jump". You need to keep track of where the rotor is, that extra piece of state. But with "followed by" it's easy, you just have frequency modulate the "followed by" expression.I put up a snapshot of this prototype,Here are all the examples I've sent so far, just click to load:For some you'll need to check the "followed by" box(es) to make them go.A note on performance: on my computer some of these are choppy, but if I go into full screen mode (button in upper right, to the left of Outline) it runs smoothly. So I think all the editor interface (outline, codemirror, react, etc) is the slow part, which should be tractable to optimize. And embedded diagrams (without editor) will definitely run with acceptable performance.--
