When we sold our house in NY, we left many items for the buyers at their request, along with tools, garden equipment, extra filters for the HVAC, etc.
I had my music room totally cleaned up- pulled out the large equipment racks, replaced carpeting, had the entire walk-in closet, which was soundproofed, stripped, spackled and repainted, etc.
I also left the Magic Bricks on a shelf in that closet. I figured they would go "Hmmm, magic, wonder what these really do." They were very nice people.
