Ah, a SereneScreen on my PPC...
I like it.
Works fine on my iPAQ 3955, 3975 so far...
I have a 5455 but haven't had time to install it yet.
It will probably work since it works on the above models.
It's a pretty nice job... but I have a few observations...
1) As noted above the background color doesn't transition very smoothly. That would go a long way to making it look more realistic.
2) I think I would like it better if the fish were smaller. That would also allow more of them to be visible at the same time.
3) A "landscape" mode would be nice.
4) Sounds? If there are any I can't hear them.
5) During the install I was asked several times If I wanted to overwrite some files that were already installed. The software should only offer to do that if the files are newer than those already there... IMO of course.
Over-all a nice effort. Still needs a little work before I buy, but it's a nice considering the limits of the platform. Would be nice if there was more info, and screen shots on the site. My buy now finger is poised and waiting.
