I just consider this a toy (just like the previous implementation). The melting is a super fun feature indeed. Try drawing and upside down capital lambda spanning the entire canvas:

     _    _
    | |  //
    | | //
    | |//
    |__/

Try not to draw perfect lines. At first the iceberg has the two tops standing out, which is fun, then as it melts and starts breaking a part around the thinnest parts, it is super fun to see how it reacts. Eventually you will end up with a bunch of slim topice floating on the surface.
