Abstract Thursday: Manmade

Here's my offering for Ingeborg's AT challenge this week, on the theme "manmade". It started off as a photo of an old thermionic radio valve (remember those? - you may not if you're less than 50 years old, although Son#1's guitar amplifier does contain at least one and it's only about 30 years old). Then it underwent a certain degree of manipulation in Photoshop to produce this multiple, composite image. I did have fun messing with it.
