+Jedan oblik, jedna boja. Ovo je program koji mozda generise takvu sliku, mozda ne.
+Radi na sansu, preko `chance` promenljive se kontrolise da li ce sansa da svi 
+budu isti oblici i boja, a verovatno nece biti. 
+
+Svake sekunde se dodaje novi, svake sekunde postoji sansa da resenje ovog zadatka
+propadne.
+
+Sada kada razmislim, ovo bas i ne radi tako, ali u nekom sirem smislu radi. Samo
+sanse nisu to sto se misli da jesu. Bice neki bugfix.
+
+Dostupna je i 2D kamera. Tako da sto duze traje, ako se dovoljno odzumira greske
+se i ne vide iako ce se kad tad pojaviti.
+
+Nisam se setio necega kreativnijeg
+pod ovim ogranicenjima.

+EN:
+One shape, one color.
+This is a program that might generate such an image, maybe not.
+It works based on chance, with the chance variable controlling whether everything will be the same shape and color, though it's unlikely.
+
+Every second, a new object is added, and each second there's a chance that the solution to this task will fail.
+
+Now that I think about it, this doesn't quite work as expected, but in a broader sense, it does. It's just that the chances aren't quite what one would think. There will be a bugfix.
+
+2D camera is also available. So the longer it lasts, if it's zoomed out enough mistakes
+won't be seen even though they will eventually show up.
+
+I couldn't come up with something more creative under these constraints.
