Here's an ICS-based, resized Asus Weather widget. It is still a bit of a work in progress as I completed some of the modifications late last night and may not have worked out all of the kinks yet. If you give it a try, let me know how it works for you.
I spent a bit more time with it today and completed the re-sizing for both landscape and portrait modes. I defaulted the size to 4x4 instead of 4x3 so the daily forecast is displayed by default. Re-sizing to 4x3 removes the forecast. I added drop shadows to the daily forecast weather icons and made the background image used behind the forecast transparent. I also tried my hand at changing the default settings, so the defaults for this version of the widget are to update every 2 hours and display the temperature in Fahrenheit. I have attached a deodexed & signed version of the original ICS Asus Weather widget for those who do not have it and would like to compare.
An updated revision of this widget is now available here
I should probably start a new thread for this and include screen shots, but this post will do for now.
