I tried doing that, and here’s what I got: (time (snowflake/inner-fractal 728)) : cpu time: 14775 real time: 14874 gc time: 2304 (time (freeze img1)) : cpu time: 377110 real time: 377867 gc time: 198343 (time (snowflake/inner-fractal/draw 728)) : cpu time: 24257 real time: 24267 gc time: 5852 Where snowflake/inner-fractal uses 2htdp/image, the result of that call is defined as img1, and snowflake/inner-fractal/draw uses racket/draw.
