Hi all,
Now that I have some time, I picked again on ShinyCocos and I fixed some nasty bugs that caused random crashes. The latest release (which I hope to be able to release this week) even comes with an XCode template, so it's really easy to start creating ruby games for the iPhone :-)
My last tests are showing that this version is really, really stable (and fast!). You can check the code in my git repo:
http://github.com/funkaster/shinycocos
best!
