Some easy peasy ZBLL cases

I finished editing this a month ago, but I had problems rendering it. So sorry for the wait. This video shows what I think are the easiest of all the ZBLL cases. They all have 2x2x1 blocks, and nice algorithms. Images grouped by the algorithms’ mirrors and inverses: Algorithms shown in order of appearance: 1:34 r U R’ U’ r’ F R F’ 1:37 l’ U’ L U l F’ L’ F 2:06 x R’ U2 R’ D2 R U2 R’ D2 R2 x’ 2:13 x’ R U2 R D2 R’ U2 R D2 R2 x 2:39 R’ U R U
