Jaxbot from WindowsPhoneHacker has posted this preview of his Home Brew Lock Screen Widgets for Windows Phone.
He notes the project is coming together nicely, with a beta arriving soon. The new version is is a complete rewrite, and Jaxbot is polling for ideas on taking the UI forward.
He also notes that the project has proven very popular.
With the Windows Phone 7 branch of Windows Phone development basically abandoned, there may be increasing role for hacks and home brew to take the existing range of devices forward.
If you are interested in the further development of Lock Screen Widgets let Jaxbot know your ideas at WPH here.
