A great gift idea for your granddaughter who enjoys experimental/avant-garde could be a canvas and acrylic paint set. Encourage her to create her own experimental and abstract art pieces. Additionally, you could get her a book about avant-garde art, such as "The Shock of the New" by Robert Hughes, to inspire her creativity. If she also enjoys music, perhaps a subscription to a music streaming service that focuses on avant-garde or experimental music can be an excellent option. Finally, consider purchasing tickets to a local art exhibit or museum showing experimental works. This can provide her with an opportunity to learn more about the art forms she enjoys, connect with other artists and art lovers, and gain inspiration for her own work.
Or you can get her a star map with the date when she was born.
