+*Animacyjne Dojo* is a presentation I gave for Digital Night Studio at Lodz University of Technology, focusing on gameplay animation. It provides an overview of the fundamental principles from a gameplay animator's perspective,
+addresing daily tasks and unique challanges. The presentation covers essential animation exeercises such as *the bouncing ball* and *tails/squirrel*, offering tips and tricks for each. It concludes with resources and guidance for those
+looking to learn animation and start their careers in the field. (*Presentation in Polish*)
