Last month's theme (circles) did not prove too taxing so I'll see if squares are more of a challenge. I'm not sure how long this obsession with geometrical forms will last - am I going to be looking for dodecahedrons come the summer? To be honest, I've had it in mind to photograph the four chocolate bars ever since I received them and the will power that prevents me eating them is steadily diminishing. I doubt they'll last till Easter.
