@ed_boner - Freezes and lag is not caused by transitions , I used this modded transitions a couple of months before posting it here and I never experienced freezes or lag .

If you want an even better experience on N900 , install Swappolube and CSSU , and I would suggest you overclocking your device as I did (1000mhz) but I don't want to be responsible for any kind of damage so if you want this , you do it on your own risk . Swappolube and CSSU are harmless .

@Cooler - If you mean blur , I've made this file for you but I personally don't like at all that blur because it screws the smoothiness .
