Thanks for raising this one here... I found Keyshape the other day and came over here to see if anyone had done any integration between them.
For me Keyshape seems a bit like GSAP but with a UI. Compared to Hype I do like the editing of SVGs - although nothing really seems to allow me to bring in an SVG externally and then animate the points in the SVG (eg bring in a curved line and then draw it. Like you can do in Hype... but only with things made in Hype.
I embarked on trying to figure out Blocs vs Sparkle vs Pinegrow and Hype vs GSAP vs Keyshape... trying to figure out what my toolset and usage path would be. And have finally found the answer...
Yes, I need all of them (ok, most of them) because they all do good things. And all have relative strengths. So I will end up using them in conjunction with each other - and this post is a great example of it.
@jonathan - in addition to SVGs being first class citizens in Hype, when will we be able to (never is a valid answer) zoom in/out in hype using the touchpad rather than a dropdown?
