Ingeborg hasn't set a specific theme for this week's Abstract Thursday challenge as it's the first Thursday of the month.
I decided to continue my blip series of photos related to the work currently going on to replace our roof. So I took a photo of the skip which now contains a lot of junk, including loads of pieces of broken wood.
It looked pretty boring so I spent a happy 10 minutes abusing it in a variety of programs including NIK Color Efex and Artistry ("Expressionist" preset) as well as Photoshop and Lightroom.
Hope it's not too psychedelic - but I was a teenager in the 1960s (although I hasten to add that I didn't partake personally in mind-altering substances!).
