Optical Illusion Lindstrand style

A scurry to Oswestry this morning to pick up a missing parcel took us past the wonderfully yellow Lindstrand balloon building. It was gleaming in the bright sun and so became the subject of todays Blip.
This is probably not the first image I was going to use but after cropping I became rather attached to this optical illusionary photo. No matter how much I know it is rectangular it still doesn't look quite right.
