Minimalism

Was not sure whether to interpret Wide Wednesday theme of Minimalism by subject or technique. 
As a subject, this car definitely demonstrates motoring minimalism. I have travelled in one of these cars and it was a slightly unnerving experience.
As for technique, I thought the barbed wire coils on the wall round Perth Prison fitted the bill (see extra) and perhaps it reflects the minimalist outlook for those on the wrong side of the wire. I like the wee heart shape at the top of the right-hand upright - such a nice touch for the inmates!
Many thanks to Freyjad for hosting this challenge.
