I was thinking about that when I bought my pinenote - imagine Tom Riddle's diary helping you with mathematics. Sadly I lost interest in the Linux side of the pinenote as it took a while to get to a working state and now I've got other things going on.

> imagine Tom Riddle's diary helping you with mathematics.

Your tone suggests that this wouldn’t be horrifying so I wonder what you meant by this.

Simply that it writes back and helps you along. hints might fade in after ten seconds of you staring at the problem.

I was referring to the visual experience, not the dark lord possessing people.
