+## Todo
+- Rewrite & optimize simulation code, store all points/velocites in one array and submit once
+    - Consider modelling each particle and all its relevant data points individually
+    - Submit each relevant data point by pointer offset, size of struct is irrelevant as long as it is constant, only necessary data will be submitted to kernel
+- Add linear beams
+- Add environment objects / multiple rooms per screen
+- Add timed events
