Andy's got the iPad port far enough along that you can sort of play the game now. Here's a short video:
There are some basic hacks going on; for example, right now, we are not drawing the real sky; it's just solid blue. Also, right now we are just loading this starting area, but it should not be long before we can load the whole game (Salvador wrote the streaming system a while back and we have been testing it extensively on the PC, so for the iPad it should Just Work. Famous last words.) Also, as you can see, the panel-tracing controls could use some work.
When we can wander around the island generally, I'll post another video update!
