I bought myself a Lisp toy as a Christmas present, a Cardputer uLisp Machine.
The M5Stack Cardputer I ordered is a card-sized portable computer based on the ESP32-S3 that runs uLisp on the bare metal. The device even has Wi-Fi, a keyboard, and a graphics display. Given the system constraints uLisp comes with a surprisingly capable and rich environment, as well as lots of libraries and applications.
A long wait begins.
