Acrylic painting on LEGO® Bricks

What to do with used, dented, discoloured, broken LEGO® bricks? Some people put them in the bottom of the cupboard, some throw them away. I hang them on the wall for all to see. 

One part of the creation is made of colorful LEGO® bricks, the other part is made of old LEGO® bricks used as canvas and painted on them to create an artwork with a special sight and effect.
