The video shows a first-person view of a player in a game, where the player is standing in a room with wooden walls and a blue floor. The player is holding a glass block in their hand and places it on the wall, creating a transparent block. The player then moves to the other side of the room and repeats the action, placing another glass block on the opposite wall. The player continues to place glass blocks on the walls, creating a pattern of transparent blocks. The room is well-lit, and the glass blocks reflect the light, adding a shiny effect to the walls.
