Another light bulb moment

I saw this beautiful Aubretia growing over an old red brick wall when I was out this morning and was compelled to photograph it. I had to think carefully how I could present it though as Countryfiles had already shown a carpet of Aubretia earlier this month. Then it came to me - my light bulb moment... wouldn't it be wonderful if we could actually buy light bulbs painted like this one? A business opportunity for someone perhaps... It would create a wonderful mood lighting effect for a bedroom or bathroom, don't you think?
