The T in Toymaker

[Accordion Twome]

I was looking around the web and found this: http://www.dandwiki.com/wiki/Toymaker_(3.5e_Feat)

I would like to make more examples.
This can be for the real world or dnd.
I'll start:

Everyone's glasses: when put on these glasses automatically fit and readjust the lenses so the user will have no trouble seeing. Can also readjust to the current user's fashion so s/he will not need to change the frames.

That wiki...

Also, this should really be in homebrew.

Teapot of the excellent host:

This teapot brews and pours tea upon utterance of a command word. This allows a tea party host to maximize conversation time.

Orator's quill:

This quill will, when commanded, write down whatever the commander says. With a concentration check, you can have the quill write what someone else says. Must be supplied with paper.

One time in a game I was running a player asked if her character could have a dress that changed color. So based on that:

Coat of Many Colors:
This coat, or shirt, or dress, can change color upon the wearers command, changing the pattern on the fabric, and becoming clean when the color changes.
