I got fed up with the Blur Gallery app. It's laggy and kinda choppy when zooming.
So I grabbed the Gallery3d.apk from my old Nexus One, running CyanogenMod 7.1, and it works! Smooth, fast, and pretty.
I'm pretty sure it's just the stock AOSP gallery, with perhaps some code tweaks from the CM team.
Here it is, if anybody wants it.
