Trinketcore (or I-Spy ) is an aesthetic characterized by its heavy emphasis on kids toys, handcrafted imagery (eg. collage and maquettes), charming and cozy atmosphere by the use of crafts, game boards, lamps, space, stars, and yellow lights. It is based on childlike imagination using techniques such as stop motion and 3D illustrations of papercraft-like objects (especially in video games).

Trinketcore has a muted color palette with glow-in-the-dark elements and browns. Blues and purples are common in room decor and are used as a replacement of black. Lighting is more yellowish and usually is created by the use of lamps with this tone. Stars and space in general are a very common theme in this aesthetic. The main visuals of Trinketcore consist of odd, mismatched or old objects used solely for the purpose of art. This can be vary from many things like junk piles to little buttons. All these aspects give off a nostalgic effect for the viewers.
