It does look like it’s pretty functional as is though. It’s one of the closer Flash alternatives I managed find that’s open source. I find despite all the hate Flash got, it was an amazing piece of technology. It was fast, easy to use, and people made a lot of amazing stuff with it because the barrier to entry was really low. I imagine Flash helped a lot of people learn to program as well because they’d start picking up a bit of scripting here and there playing with it.
There really isn’t any popular alternative to Flash today, and I think that’s kind of a bummer.
