'A swan cuts through the zigzag reflections on the River Mersey' Photograph: Larry Higgs

'As I was coming down the tower at a fabulous service station off the A16 at the Baie de Somme, France, the sunlight created an op art view I couldn’t resist. I remember it with nostalgia every time I stop at an English motorway service station' Photograph: Val Straw

'This is a mountain road viewed from the monastery of Sant Pere de Rodos in Catalonia' Photograph: Stephen Duffy

'This is a photo of the market building in Toulouse. It was taken around midday when we went to have lunch at one of the excellent value restaurants upstairs. The high scorching sun created heavy shadows which emphasised the triangular patterns on the side of the building and the dramatic shapes caught my eye' Photograph: Richard Bown

'The zigzag breakwater at St. Monans harbour in the East Neuk of Fife is somewhat hidden, but easily accessible with a short climb to the top of a harbour wall. Though on days like this your reward will be regular pelting with seawater sprays' Photograph: Mathew Schwartz

'The bows of the moored fishing boats make a great zigzag pattern. These were in the harbour of Essaouira, Morocco on a sunny February morning' Photograph: Ange Andrassy

'I loved the contrast between the traditional Flemish buildings and the beautiful blue sky in Bruges' Photograph: Alison Mitchell

'Dig those diagonals - zebras at a watering hole in the Serengeti, Tanzania. Note the little bird on the back of one of the zebras' Photograph: Richard Peoples
