I'm sorry for your loss too, Kadri. So young... The worst feelings will last a (long) while, but you never completely get over it. A youth friend of mine (not even a relative) committed suicide (because he couldn't get over the sudden loss of his rather young mother). This was 30 odd years ago, but sometimes I think of him and get sad again, and it's not even close.
On the experiment; I might figure out how you did this (warping, a cube, 2+ simple shapes, some displ. of course), but I find it very clever. Respect!
