Also known as corriculum, is the name of a "language" consisting of English written with the digits of a calculator. You type in a number and then turn the calculator upside down to see the word. In order to make use of all ten digits, I persuaded the Anglo-Saxon letter eth (ð) to return from retirement to stand in for 'TH'. For instance:

Here are the 10 letters of Oðblgshezi:
I 1
Z 2
E 3
H (h) 4
S 5
G 6
L 7
B 8
TH (ð) 9
O 0
HOE - 304
Hello - 0.7734
Hi - 14
