Hi Folks,
I already hacked a webcam support for Squeak@Linux, 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/2411And 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?
