Mixer, Python, Wendeltreppe
Ich kam mit der Idee, Würfel spiralförmig anzuordnen, zu beleuchten und die Kamera zu drehen.
Insgesamt gibt es 124 Zeilen, von denen etwa 20 Würfel sind. Der Beleuchtungsteil und der Kamerateil werden von anderen wiederverwendet. Ich bin der Meinung, dass es verbessert werden muss, damit es eher wie eine Treppe aussieht.
