Hehe, my version of Roulette is available at:
http://dev.laptop.org/~yoshiki/etoys/Roulette.005.pr
The description in the project says:
--------------------------- A remake of Mr. Yokoyama's (former principal of Wada Elementary School) Etoy for first graders. A painting with a bit of tools and just one script with one line (and tick rate change) to make a sufficiently engaging project for 6 years old.
This can be later extended to talk about angles and probability.
Notably, with this kind of simple projects as the starter, Mr. Yokoyama successfully get the eco-system where the older kids make projects and teach projects to younger kids. ---------------------------
Yes, one of the disturbing things is that I have no idea why a project never shows up on the site...
Mr. Yokoyama came to Squeakfest in Chicago several years ago and presented his experience. "Roulette" was one of projects he showed, and people were quite impressed with the effort.
Even after he retired, the "legacy" stays and they still use Etoys at the school on Saturday special sessions. He has many projects for kids and improve them always...

Let's be even more subversive and make a ready-to-view link:

Maybe this will become the 51st of the "Fifty Dangerous Things (You Should Let Your Children Do)"?

Do you recall any more detail about this, or have Mr. Yokoyama's presentation?
For example, was this project made by a six year old? What activities will be done with it?
Some ideas might be: Guess a number and see if it stops at your number. Get points when it lands on a number, then add the points of successive spins with pencil and paper Am I on the right track? Is there more?

Hmm, there used to be the blog (and IIRC, presentation materials and possibly recording were there, too) at the site of Interactive Arts and Media department of Columbia College of Chicago, but apparently they took it down and I couldn't find the page in the archive.org.

I can't give the answer from first hand experience, but guessing from what I heard, it is 6th graders try making it/them together with 1st graders (6 years old), or 6th graders made it/them and let the 1st graders play with them and extend together.
The Saturday workshop has a blog BTW: http://saturday-squeak.blogspot.com/

These are good! The original version and a version by Abe-san (http://squeakland.jp/seaside/SBSuperSwiki/86bea02b-e6a2-492e-abbe-0b078659f0...) had points.
You can put stars/numbers in some distribution and put different scores for them, and try to see the resulting distribution; Try different "turn by" values and see if the resulting distribution (after certain large number of trial) changes or not. The law of large numbers is a good thing teach, so you can have many kids do the trial 10 times each and sum the results up to get the sense of distribution variation for small number of trials and large number of trials. Instead of ticking the script, you put different value to the "turn by" script and see how many times you have to execute the script to get the one full rotation. Also for the Etoys' front, change the arrow's rotation center and make it rotate instead of the board; extend the script so when you press a button the rotation slows down instead of abrupt stop; put a color sees tile for the arrow and automatically display the score when it stops. etc., etc.
Thank you!
