An interface can be visually impressive and exhausting to use. The problem is often a constant tempo: everything arrives, moves and asks for attention at once.
Build the rhythm around the visitor's task. Introduce a point of view, then give the information room. Let an interaction respond quickly when the person has already made a choice.
Transitions should explain relationships. A preview becoming a detail, or a line becoming the next axis, tells the visitor where they are without another paragraph of instruction.
Restraint is a practical design tool. Reduce motion when it obscures content, respect different input methods, and let the person control the pace.
