Yoma 70a - the miztva of "showing off" your Torah Scroll

Here's an interesting anecdote from the Daf Yomi of last month. In Yom Kippur, all (yes, all) the people that were in the temple for the day would bring their personal Torah Scrolls the day before to have a chance of reading from it on Yom Kippur day and displaying the beauty of their scroll. 

From this Gemara we see two important concepts of the Mitzva of writing your own Torah. 

1) you are supposed to use it, be it for learning or just for Krias Hatorah. It is not supposed to be a relic locked inside a safe. 

2) it's commendable to beautify it as much as a person can, so others will see it and appreciate it. This is often called in Halacha זה קלי ואנוויהו.
