OK this is lockscreen weather and it looks like this:




1. It works with OMWeather, so you need to install and configure it.

2. Install imagemagick from extras.
3. Download Weather icons
and extract icons to /home/user/MyDocs/.Weather/

-open Xterminal:
4. Download Imagemagick Weather
and extract it to /home/user/imagemagick/

-open Xterminal:
5. Edit /home/user/imagemagick/weather.sh

6. To make it update automaticaly (every hour), make new QBWidget and import Lockscreen widget to Beecon

or

you can use:
7. OPTIONAL

If you want to remove "Swipe to unlock" do this:

-go into the /usr/share/locale/en_US/LC_MESSAGES/ (if you use some language other than en_US, search for file in folder according to your system language)
and copy the file osso-system-lock.mo to your computer. (save original for backup)

-convert .mo to .po using this URL: http://tools.konstruktors.com/
-open .po in Notepad (or any other text editor)
-search for "secu_swipe_to_unlock" and you should see a line under it saying
'msgid "Swipe to unlock"'.
Replace "Swipe to unlock" with " " and save the file.
(NOTE: "[SPACE]")

-convert it back to .mo and copy it to N900 (/usr/share/locale/en_US/LC_MESSAGES/)

Thats it...I didn't had time to find different background for every weather condition so I used same background for rain and light rain...but you can replace it with your photos in /home/user/imagemagick/ (800x480.png)

Hope you'll like it

This post was my...inspiration!

UPDATE: This is updated version of QB widget and weather.sh script. It uses less CPU and checks for OMWeather updates every 30min instead of 1 hour.
