We previously took a look at Windows Phone Hacker's Lock Screen Widgets concept, where enough interest from the homebrew community would spark development to turn it into reality. It would appear as though enough interest was received as in the above video, we can see a working preview of said concept in an app form.
Work is still ongoing to apply UI enhancements and tidying up. Adding, re-arranging and removing widgets is fairly straightforward and selecting the Bing wallpaper is also possible. Suggestions are welcome for new widgets or on the app itself. We look set to see a beta version released next week (depending on continued progress), so stay tuned.
