I'm working with the Smalltalk Renaissance Program to run a Smalltalk coding competition to start in January 2016. The competition is open to high school students across Canada with prizes of university scholarships we're calling the "James Robertson Memorial Scholarships".
The competition itself will run over 10 weeks in 5 rounds. The challenge is to write a program to play a game we devise (details to be provided later). At the end of each round, we produce a video of the top 30 scoring programs. For the next round, we throw in a twist to the game. The scholarships are awarded based on the scores of the final round.
This competition will be a lot of fun to play and to follow. All materials and videos produced will be available for anyone to download. Only student teams can actually compete.
We will be producing introductory videos to get the students familiar with Smalltalk, the development environment and the starting code we provide.
For this to work, we need the funding for the scholarships so we're running a Kickstarter project. Come join us to help make this competition a success.

Well, here's my first rendering of an OpenGL scene from Smalltalk on the Android:
It's your standard plain colored triangle on a plain background - so shoot me. But this image was generated by calling OpenGL primitives from my Smalltalk VM on an Android device, so it's pretty special.
I've talked about this Smalltalk before here. Here's the current status. I have all of the same bytecodes as VisualWorks implemented with the exception of the bytecode for thisContext. This allows me to use the VisualWorks compiler for free.
My source code is kept in a Store package in a separate namespace. To run the code, I package all the classes and methods from that package into an image file in my own format - the Android image isn't compatible with a standard VW image. This image is added as an asset in an Android project and sent along with a .so shared object library for the VM where it runs on the Android.
There's no Java code in the project at all. I'm using a native activity in C and I've merged the Android event loop into the Smalltalk interpreter loop. This allows me to handle events from the Android although I currently don't have code for that.
For debugging purposes, I can package a development image. On startup, this image connects by a socket connection to a VW application which I wrote to provide low-level debugging and stepping instructions.
The system is still in its infancy. There are still lots of things to develop like the garbage collector and most of the class library. I have some basic operations but there's a lot of work needed to build up the library. So far I don't have large integers although that's in the works. I do support Float and Double and these classes are being used to help build the OpenGL image above.
I'll be demoing this system at Camp Smalltalk in Vancouver. I'd be happy to answer questions about it. It still needs a lot of work, but it's starting to produce real results.

Everything's booked. My wife and I are heading to Nanaimo BC on October 3, 2014 to attend Camp Smalltalk. I'll be demonstrating the mobile Smalltalk I'm developing - it will be a work in progress. I may also be involved in a "Intro to Smalltalk" presentation there. I'm heading back to Ottawa on October 6th.
If you're interested in attending, you can check out this link:
