05:52 <Chwoka> HTDP: got to the part where it wants me to use big-bang from world.rkt in combination with the square-drawing function from 2hdtp\image.rkt. but DrRacket throws up an error and makes me pick one or the other every time i try to load both of those teachpacks at once, it says they "conflict" and specifically: "(the export add-line is in both)"

07:32 <Chwoka> figured it out: i got mixed up somewhere, i was supposed to use universe not world
