I cannot find any option for it, but was wondering if "playing" of Event Theatre can be "saved as" or converted to a video format such as ogg. I realize one can use a screencast software to capture that section of window but that seems to be a 2-step process, external to etoys..
Thanks Milan

That would indeed be a very desirable feature. Right now it's not supported. Event theater only records events (including voice over) and plays back by re-executing the events.
What could be implemented relatively easily is to store a series of pictures while playing back, and save the audio as a WAV or similar. Then you could use an external tool to create a video from that.
Even cooler (but probably much less simple) would be to use the new GStreamer support to encode an OGG video directly from Etoys. That could really give "one button publishing". Let's see if someone tackles this :)

Thanks for your comments - Interesting. I would not know where to start, but maybe one day ... in relation to that, would it make sense to tackle it in the new (Tweak-based) Etoys - I am not sure it is on the radar.

Maybe :) At least we are trying to make contributing much easier than before. If you have thoughts on what could be improved to invite more developers, or make it more approachable for the current ones, please let us know.

Well, nobody is working on Tweak-Etoys currently. It is functional and it demonstrated quite a number of benefits over Squeak-Etoys, but it would need a lot of polish and engineering to make it useable day-to- day. Unless someone takes on that task it will remain a prototype.
Squeak-Etoys will be maintained and further developed outside of VPRI in the future. VPRI itself now focuses on inventing more powerful approaches to end-user programming, which may (and hopefully will) result in an all-new Etoys a few years down the road.

Bert,
first, thanks for sharing status of Morphic, Tweak Etoys, and hopes/plans for a potential future (fonc?) version.
Well, I took up your above invitation to share thoughts about how to attract more developers (and users), and did put together a point-by-point list of things I have been thinking about in the past few years (list is longer than it's worth, but what's done is done :) )
None of this is innovative or new, but it summarizes what I have been thinking about. Much of the stuff below requires hard work and foot work of all who take interest in Etoys - and perhaps some application of "The Tipping Point" approach - And I am feeling bad for not having done for Etoys as much as I wish to ...
So, some points:
============ # 1. Make best use of the delivery railway (browser) to have "Etoys Everywhere" ============
- Overall motivation: Clicking on .pr file anywhere should start Etoys. This is nicely on it's way thanks to the Etoys HTTP plugin. A few more related things :
1.1 - The Etoys HTTP plugin is extremely important : http://www.squeakland.org/download/. How can we make it ship by default on as many browsers/OSes as possible? How to make as many browsers aware of etoys files (mime type? .pr extension?)
1.2 - Why not to ship OLPC browser with Etoys HTTP plugin. Right now, browser on olpc saves .pr file to journal, but it does not open (this may be something wrong with my setup).
1.3 - It would be cool to have Etoys plugin listed in the non-javascript plugins for Firefox - Firefox has 20% of word browsers share and thousands browse this daily: https://addons.mozilla.org/en-US/firefox/browse/type:7 - somehow this relates to list on http://plugindoc.mozdev.org/ Maybe we need to ask the maintainer to point to the HTTP plugin directory? I will do that ...
1.4 - What does it take to add Etoys .pr to the Internet Media Types Registry? ftp://ftp.iana.org/assignments/media-types/ Would it help?
1.5 - Google Native Client could be of use as delivery railroad as well: http://code.google.com/p/nativeclient/?tbbrand=GZEZ&utm_campaign=en&... et-osrcblog&utm_medium=et
============ # 2. Multiply Developers and Users (this should be #1) ============
- In open source projects it seems the most useful are those where developers are also users (development tools etc). This synchronicity is difficult to achieve with Etoys where target audience are Grade 1-8 teachers. Maybe one needs to start from the "top", by targeting audience who can help Etoys development and content creation - university and high school students and teachers.
2.1 - Increase Etoys/Squeak usage at Universities and High Schools. Nice to have more sites like EtoysIllinois! http://www.squeakcmi.org/
2.2 - Show Etoys to Teachers at Teacher Colleges.
2.3 - Encourage School boards to accept Etoys as part of curriculum. It is difficult for teachers to go against the flow. I have heard the "teacher asked us to present our project in power point" many times from my kids.
2.4 - Maybe there are some government initiatives with less focus on testing and more focus on creativity? I read something about 3 months ago but lost the link...
============ # 3. Motivation - Kids and Adults ============
- Find creative ways to find new users (teachers, students)
3.1 - Enable motivation of kids to explore Etoys on their own. Make etoys more suitable for writing simple games. (I still miss ability to move a Morph with arrows!) I really believe games-friendliness is very important - there is nothing wrong with allowing kids do what they like to do, to help them explore other things using tool that allows better education as well. Sort of like using sports to attract to education :) - interesting note on games: http://rupert.id.au/schoolgamemaker/attitudes.htm
3.2 - Let us not separate Etoys and Squeak too much, to increase awarenes and maintain potential developers pool. Also, it is always good when people can make living by what they like doing, so more Squeak industry marketing. Unfortunately, mankind loves repetition too much. With wider Etoys usage, the (miss)motivation "let us teach Powerpoint because that's what kids will use in they work" should go slowly away.
3.3 - Squeak and Etoys is beautiful, innovative, going in the right direction etc etc - so let's not be afraid to say it, and market it a bit more :)
============ # 4. Bigger Picture that cannot be solved by Etoys: ============
4.1 - Better physical interface (rather than mouse/keyboard). Something like OLPC with a 3d glove :) or something like wii (etc)
4.2 - Goal of education should not be 'to measure' but 'to create'
4.3 - School system should allow teachers who want to step out of the box to do so...
etc
Well I hope this does not sound like some sort of manifesto .... i just wanted to list all i had on my mind for a while...

The simplest thing would be a script that take a screenshot at a certain frequency and save them to a folder. I'm not sure how many frames per second that would give though....

I will give it a try - I made my video allright but this is interesting experiment eve if it shows to slow/jerky.
