Well, a couple months ago I read this paper: http://infoscience.epfl.ch/record/176887/files/DeprecatingObservers2012.pdf I got inspired and Hacked up a morph that draws when you click on it, using the following code: Reactor loop: [ :reactor | | path | path := PathShape vertices: { (reactor next: RMouseDown) position}. self draw: path. reactor loopUntil: RMouseUp with: [ | move | move := reactor next: RMouseMove. path addVertex: move position. self draw: path. ]. self finishDrawing. ] on: self announcer. p := RReactivePolygon new. w := p openInWindow. w extent: 400@400. Of course it was just a dirty start, but if it is of use to anybody, here is the code: MCSmalltalkhubRepository owner: 'Guille' project: 'playground' user: '' password: '' On Sun, Nov 2, 2014 at 12:42 AM, Skip Lentz <skip_meesie@hotmail.com> wrote:

That sounds like a cool idea.

I found this through a quick Google: http://ss3.gemstone.com/ss/FRP.html, but not much else..

Doesn't seem to be in development anymore either.

I was reading https://gist.github.com/staltz/868e7e9bc2a7b8c1f754

It looks like that this is where the new apps are going.

Do we have anything on that Rx front?
