I've been playing quite a bit of Lumines Live on my 360 lately. I'm no Mr. HeXic, but I recently posted 111 deletes in 60 seconds. This puts me in the top 100 on the Live leaderboard, so I recorded the replay and built a WPF/E video player to host it here. I used Expression Blend to design the skin and Visual Studio to add interactivity. The source for this video player is here and the direct link to the sample is here. I plan to update the video if my top score improves.
