Thanks for pointing us to this project. (Actually, thanks, too, at least from me, and very
sincerely—a phrase that normally suggests its obverse—for posting your rumination on AOO
in the world, which I'll be not-quite-savaging shortly. Actually, not savaging it at all.

A few points on this Kivy….

* What it is, from GitHub: 

<quote>


Innovative User Interfaces Made Easy.

Kivy is a Python framework for the development of multi-touch enabled media rich applications.
The aim is to allow for quick and easy interaction design and rapid prototyping whilst making
your code reusable and deployable.

Kivy is written in Python and Cython, based on OpenGL ES 2, supports various input devices
and has an extensive widget library. With the same codebase, you can target Windows, OSX,
Linux, Android and iOS. All our widgets are built with multitouch support.

Kivy is MIT licensed, actively developed by a great community and is supported by many projects
managed by the Kivy organisation.

* The docs are indeed remarkably good. But so is the architecture of the project and I must
assume the code itself that does things. There are several good things in Kivy that I wish
we had more clearly laid out on OpenOffice. These include philosophy, architecture, and other
useful abstractions. In addition to the docs page you cite, there’s also O’Reilly; see:
http://shop.oreilly.com/product/9781783281596.do


* I’m particularly taken with the philosophy page (http://kivy.org/docs/philosophy.html#philosophy),
as it explains the raison d’être of the project. And it’s not just marketing churn. (A
similar, persuasive claim is made with the Meteor project, in its assertion of utility over
Angular JS, which remains overwhelmingly popular.)

* I can’t weigh in on whether it would be a good replacement for VCL or even an alternative.
The claims made by Kivy, however, suggest that its use would open opportunities.

* One conceivable drawback is that Kivy also uses "Kivy Language, for creating sophisticated
user interfaces[,]" though it does not seem to be required for creating naive UIs. Kivy is
in Python and their conference presentations seem to be mostly at PyCons. One might wonder
about the use of Python for something claiming speed as a virtue. They answer that worry in
their Project FAQ. See http://kivy.org/docs/faq.html#why-do-you-use-python-isn-t-it-slow

* Kivy is still new. It doesn’t seem to have a Wikipedia entry (Ye Gods!)—nor does it
seem to have a separate foundation supporting activity; Google Groups and GitHub seem to do
the job. There also does not seem to be any major sponsor. Actually, from these points one
could draw the line suggesting a nearly perfect open source project, at least in the international,
direct-democratic/meritocratic and kind of friendly sense. But nothing this side of the Eden
is perfect, so I’m probably missing something. :-)

* Did you contact the Kivy Project? The website is at http://kivy.org/#home . 

* Finally, one thing I discovered earlier was that "fun" projects that could be useful but
need not be are excellent ways to include more contributors.

Cheers,
louis
