I decided to give my new (experimental) programming language, codenamed DALIS a try on some other platforms.  This one is obvious I guess - the good old iphone:

...but I was pleasantly surprised to see it working OK on my PSP as well: 

The fonts on the PSP don't come out the same, but it seems to run OK, which is the main thing.  I would be fun to try a Kindle, but I don't have one (yet).  The advantage of a cloud-based language like this is that you only need a browser, so it should work on all kinds of things.
