PDP/Summer Reading

Over the summer break I have been reading texts to help me refine my ideas, I have been focusing on works by Jasper Johns in relation to Duchamp, as recommended to me in feedback received before the end of term. I feel that this is possibly not the direction I want to go down, as I am more interested in function removed to create art works and I think I want to look at functional art. I am quite unsure about what I want to do, and have e-mailed my tutor but had no response.
