Really depends on how much you want to spend + your current house design.
Option 1 - Covered Hollow Cabinets
Ikea cabinets
Complexity Level : Simple - Moderate (fixing Ikea stuff usually frustrating)

+
Black white photos to cover the holes (still have space to put things)

Option 2 - Pallets
Complexity : Simple - Easy (just don't wood pricking your fingers ; might have to sand the pallet to give it a smooth finish)
Take a couple of pallets (weighted it at the bottom so it doesn't topple over) cover it with pictures

Option 3 - Japanese room dividers
Complexity : Dirt simple (Pay money and get it delivered)

Option 4 - Fixed Separator
Complexity : Moderately - Frustrating (talk to carpentry person to do + co-ordination + cost more than the above)
Floor to ceiling metal poles on each side ; and put a zinc sheet (minus holes) held both sides with couplers on the poles. Can use as a magnetic board and stick notes, photos, etc on it.
