4. At the start of playing this, I pretty much just clicked on as many buttons as I could and scribbled with them to see what is possible within the game. I was very surprised when I clicked the plus button and began to draw. At the time I also had the rainbow color selected, so what I saw was a circle that was quickly changing between the colors of the rainbow and gradually increasing in size until it covered the entire screen. This was a very unexpected result, so I began to experiment with it. My favorite result came from starting with the +/- brush as the size of the screen, and then clicking minus and simply holding the cursor in the center of the screen. This resulted in overlapping rainbow circles that gradually got smaller, creating a series of rainbow colored concentric circles filling the screen. Such an elaborate image created by simply holding the cursor in one place was very cool. It required no artistic skill, just the willingness to explore what the different tools of the game were capable of. This concept also gave me more ideas for what I could have done in my game. Specifically I thought about a brush that moves from thin to thick, but when it reaches a certain limit would get gradually thinner again. This would be the same concept as the one in this game but with a smaller range and less control by the player. The +/- tools in this game really interested me, so after I discovered them, they were all i wanted to play with.
