Press the green flag for the first view. Press the space bar for a different design.
I started with one thing in mind. When I ran into difficulties, I learned new things. I captured one happy accident by duplicating the sprite; keeping the accidental code with the new sprite and trashing the code with the original sprite so I could get back to solving my original problem. I had some buggy problems in the end. Then I realized that both sprites were running simultaneously. I chose a different hat block for sprite #2. After the initial code ran (when green flag clicked for sprite #1) then I could have the option of pressing the space key (hat block used with sprite #2) to run the second design.
