Here's a nice pic of the widescreen version running on my 51 inch HTPC. For perspective, I put a CD on top of the TV (monitor?)
I'm running this at 1280x720 and it's smooth as silk (500Mhz PC w/Geforce2).
If you've not seen the widescreen, notice how the bubble column is on the right, and there's a few extra clams/rocks in the middle. Most importantly, notice how the fish are still at the correct perspective. When I run MA_Time (whatever it's called) or MA2 on a 16:9 ratio screen - everything looks a little squished. ....can't wait for all the goodies mentioned above.
