But it´s either the original or the sorted result. So a animation or a warp or at least 75% between would be nice.

you can have 2 array : the unsorted, and the sorted. then interpolate between 2.

this is still a lot for real time in the CPU.
but if you find a way to store the 2 array in the GPU (using texture), and interpolate with a shader, then you will be fine.

i think Iohannes ask what is a 75% sorted list.
