There is one source I follow to keep up with app happenings in the Windows Store and that is McAkins Online.

They keep a very close eye on the store and always discover when the latest and most unique apps become available.

In keeping with that trend today they discovered a real gem – mostly expected based on previous announcements – but a nice find none the less.

Description: Project Spark is where players create and creators play.

The ultimate interactive playground for gamers of all ages, delivered as a free digital download with many options for enhancing your creative experience, it’s a place where you can walk in the world’s collective imagination and start playing. See how a creator did what they did, and when you’re ready, become a creator yourself. Project Spark is a powerful, yet simple way to build and play your own worlds, stories, and games. Share all of your creations to a dynamic community, and play what the community makes. Project Spark brings creation to life and presents endless opportunities for play.

The Project Spark Beta is a preview of the final game, which is scheduled for launch in Spring 2014 on Windows 8.1, Xbox One, and Xbox 360. For a limited time, the door is open for you to make the kinds of games you’ve always dreamed of, play the games created by a global community, and shape the future experience for Project Spark. We want you to identify the limits of what Project Spark Beta is capable of so we can push past them.

Here are some of the screenshots, courtesy of McAkins Online, from the Windows Store listing:

According to McAkins Online beta codes will be sent to individuals that are signed up at https://joinprojectspark.com/ once the app goes live for everyone. If you want to look at the store entry for yourself it is visible on the web but that is it until it hits the Windows Store for all regions.

Nice find guys!
