Matt Worden, of MWGames.com, has recently moved in and set up a blog for his new project Nimble2D.
I'm looking forward to seeing what he comes up with. Here is the description, in his own words:
Nimble2D is a 2D game development library for .Net based on SlimDX and DirectX9. It will use Direct3D9's Sprite functionality to create a fast 2D environment (with real-time rotation, scaling and blending), mobile cameras, sprite-based text and primatives, and real-time sound effect panning and volume based on sprite locations.
