Pi Cubed is a visual math application for the iPhone / iPod touch that lets you perform calculations as you would on a piece of paper.
This app looks very interesting both in the problem that it solves and how it allows you to do so.

OS X refused to let me empty the trash as it contained TimeMachine’s Backups.backupdb directory. It simply complained that there were BootX files present. The trash could not be emptied with an option-empty, either.
I found this solution to work fine; which involved rm -rf’ing the .Trash dir in my home directory (which was unnecessary) and more importantly doing the same in the Trashes/<my uid> dir on the external drive in which that trash had lived.
foof explains why here.
Here is the main page for Pharo Smalltalk; it looks pretty interesting.
From talking to a Squeak maintainer; I got the impression that a lot of Squeak developers and maintainers feel sort of a love hate thing with Squeak. On the one hand it has so much history and it is such a great tool that they loathe change. On the other hand, the inability to change things is the biggest issue in moving forward.
