Custom creation of wall decor using a device configured to display an interactive wall art environment. The interactive wall art environment incorporates a user photo of a furnished room, including a background wall and a scaled image of the furniture in the room, and a curated layout of items displayed in proportion to the scaled image of the furniture to simulate the appearance of the wall art in the furnished room. The user can alter the wall art environment as desired, including selecting a custom wall color and a predefined image of furniture to simulate a furnished room instead of using the photo of the furnished room. The display of the interactive wall art environment includes displaying the cost of purchasing the customized items in the curated layout and linking to a shopping interface for transacting the purchase.
