Oh, that looks great, Diego! We'll definitely will try to get it
working :)

Hi Folks,
I already hacked a webcam support for [EMAIL PROTECTED], it's named
"Video4Squeak".
http://minnow.cc.gatech.edu/squeak/3765
It uses Video4Linux, so I think is posible to run it in OLPC.
The camera also support some toys programming features. I also got
working the Intel(Play) USB Microscope (except for the ligth, the
linux
module seems to be broken).
In the screenshot you can see 2 webcams (in fact is one plain
webcam and
the Intel microscope) capturing at the very same time.
My work assumes the morph will survive the camera disponibility
(you can
move the squeak image or a .pr to another machine without camera,
or if
you connect more than one camera the order in USB stack can be
different
in different boot-processing, etc) and it makes a good job trying to
reconnect.
In etoys vocabulary, you can find a "lastFrame" property. This
property
answer a SketchMorph that you can embed into a container and create an
animation. I used to create a project where one (etoys) script
capture a
frame between time and time (normally 30 seconds) and put the frame
into
a container. Another script just plays an animation (using the
captured
frames) and instantly you have an accelerated-video (this type of
videos
where a flower grows really fast, etc).
The plugin interface is relatively simple, so it's quiet posible to
get
(the plugin) working in Windoze.
Attached is an screenshot showing the complete etoys-vocabulary.
Let me know if this helps.
Cheers,
-- Diego

Really cool.
Does Etoys/squeak have support for cameras? We got that running
today...
Well, there is "VideoFlow", which looks interesting, but requires a
plugin that might not have been ported to Linux yet:
http://minnow.cc.gatech.edu/squeak/2411
And I just received some old bits from Tim Rowledge which once
formed
a Video4Linux plugin.
How would I access the camera? And until I get a b-test, could this
be simulated by a USB camera?
