Turbo mode required (shift+green flag). Start off by typing in the number of colours to sort and then choose a sorting algorithm from the list and type it into the box. The project will then shuffle the colours and then wait 2 seconds and then start sorting. The lines indicate where different colours are being swapped. You can turn these off by setting the "show lines" variable to 0. The "mode" variable allows you to switch between stripes across the screen or them being in a circle. The "slow mode" variable allows you to slow down the project to get a better view of what's happening.
