Wrote a simple game for Silverlight platform:
http://lazunin.com/stetris_en.html
First made it in IronPython with Dynamic Language Runtime, but the
resulting file was huge (~1.15 MB packed) because it's dynamic and it
has to bring along all IronPython libraries.
Then re-implemented with Boo, it needs only Boo.Lang.dll and the
result is ~46 KB. All the resulting assemblies and sources can be
found on that page (if booc gives you some error concerning
"mscorlib", it helps if you install (update) some net 2.0 SDK or
something).
I am not really up to date with today's typical sizes of silverlight/
flash apps, but as for IronPython, is it even practical to make
something _that_ big for the web? The size of the Boo version, on the
other hand, seems pretty reasonable to me.
