I got my idea for this sample from the red bricks, i was looking at the shape and colour with in. I created this by painting onto some white fabric, i took pictures of my process and then put them together in a video. It shows the mould growing and changing colour and eventually dying out. I edited the photos in the video on photoshop to make the colours stand out.
