Olek‘s projects seem to be taking on increasingly epic proportions. For her latest yarn-bombing venture, she returned to Mother Poland to bedeck an enormous dysfunctional Px48 locomotive with her signature bursts of rainbow-camoflauge splendor. With the help of four assistants, the project took her two days to complete and will remain in the town of Lodz until August 19th. Hopefully the pyromaniac teenagers of Poland will know to stay away after Olek schooled the last two vandals who messed with her in the homeland.

Watch the painstaking process in action below. It is glorious.
