Screenshot of a terminal window running nu shell. There are happy and intense colors. First you see some lines of the end of a table with numbers. In the last line, the headings ("from" and "to") are repeated. Then there's a prompt with a file path, and the command "source 05b.nu". This is followed by an error message, which is expressive and beautifully formatted. Then another prompt with the same command (one can infer that the error has been corrected in the meantime), and a table with numbers.
