 2 | ###### _i had no idea how to name this project ^^_
 3 | 
 4 | I really like the iOS interaction to set your sleep time - so I tried cloning it.
 5 | 
 6 | I definetly could optimize the maths behind it and also fix one or two minor visual glitches.
 7 | 
 8 | Additionaly I'd like to add the interaction to rotate the entire wheel in near future.
