xda-developers - View Single Post - MIUI camera app for CM7 [New Version posted 5-28]
This MIUI camera works on my D2 running CM7.
You can read through the thread, but this post has the current/best build that works on my D2 running CM7.
Push APK to /system/app, then set permissions to 644 and owner to root/root (basically match setting of other APKs in /system/app.
Pretty cool - starts up and shoots and just works! Full-screen option (which I missed from Blur camera) and other nice features.
Video even recorded (though FC after playback and return to the camera).
