I found some old photos for the red challenges this week in Redbubble:

<Digimax i6 PMP, Samsung #11 PMP>

First for the challenge 'man-made'. I saw this in a modern art exhibition in Paris, made by ANITA MOLERINO; you can watch and lidten to explanations about her work. She uses everyday objects and deforms them with heat.

Second for the 'nature' red challenge; this is a hollyhock seen in TALMONT, Charente Maritime.
They are unusual photos but I don't know if they will be selected.
