Hello There, I have been working in OSWindow, which is a cross platform API for dealing with native operating system windows. This API requires using a custom VM and the library SDL2. With this API, even the main Pharo window is handled almost completely in image side using NativeBoost. The only support required from the VM is a small periodical check in the heartbeat about the presence of events. This no more than 10 lines of code. This is currently working very well in my Linux machine, so I need to start testing this stuff. For Windows, soon I will be building the custom VM. My last built was very dirty and I want to do something more clean. For Mac OS X, I don't have one for testing. But Alex is going allow me to borrow one for some time. So be patience. As for Woden, it is a new 3D graphics engine that I started making. This one requires currently support of OSWindow and also shows some cool stuffs. As for prebuilt versions of the VM with OSWindow support along with preloaded images for both, OSWindow and Woden. And screenshots. Well, I am putting them here: http://ronie.cl/OSWindow/ Greetings, Ronie
