Hi, I just moved "Spreadsheet" from SmalltalkHub (http://www.smalltalkhub.com/#!/~TorstenBergmann/Spreadsheet) to a community owned location at GitHub ("https://github.com/pharo-contributions/Pharo-Spreadsheet";).
If I remember correctly the project goes back to ancient Squeak times - but it was kept up to date and is basically working. So if you want to write the next killer spreadsheet application in Pharo then you might want to use this as a base. Screenshot attached Have fun T. (aka astares)
