I ported it quickly this morning, nothing major. God it looks better than the standard Calculator, and finally fits in with MIUI. Will fix the slider text issue another time but for now feel free to test on any ROM/device whatsoever, it should work just fine. Apk available here: http://www.miuiaustralia.com/?page_id=823 This is for impatient people who want it on ICS before next week . Or people (like me) who just want something different in their AOSP ROM than the boring standard one.
