I use WidgetLocker to add widgets to my custom lockscreen, combined with my RSS feed and Simple RSS Widget.
Below are the results:
I'm using "Simple RSS Widget" and "WidgetLocker" with the following settings:
1. Configure WidgetLocker however you like. Alternatively, you can just add the Simple RSS Widget straight to your homescreen.
2. Add the "Simple RSS Widget" widget to the lock screen.
3. "Manage Feeds" -> Delete all feeds -> "Add RSS Feed" -> http://gelfman.me/doge/
4. "Appearence Settings" -> Uncheck all boxes but "News Text" -> "No Images"
4a. Customize "News Text" as you wish.
5. "Widget Settings" -> "...update the widget" -> Items per feed: 1 -> Update every: 0 hours, 1 min
6. Resize and reposition as you please.
Using the above settings, you will see the current Cryptsy price, updated every minute, with the option to manually update as you please by pressing the widget itself.
