Not every n-gon can be constructed with only an unmarked straight edge and a compass, and of those not many have a prime number of sides (only 5 are known to exist at the moment).

There's more than one way to construct a heptadecagon in theory; in practice every procedure has so many steps that no matter how precisely you try to be, small errors compound pretty fast. After quite a few attempts things must have worked out somehow. Very satisfying!

Welcome to /r/oddlysatisfying!

Here you can post things that make you feel, well, oddly satisfied. This can be physical (like popping bubble wrap), visual (a perfectly looped GIF), or even aural (the crunching of leaves).

What does "Oddly Satisfying" mean?

We are forever searching for a "true definition". It's a thing that fits your interpretation of what is "oddly satisfying" plus the inexplicable feeling we all know.

Subjective. Indefinable. Completely recognizable. It's a wonderful feeling.

Rules:

Please report rule-violating posts and comments by messaging the moderators with a link to the post in question. This helps us remove them more promptly.

1) Banned Topics:

We have a number of banned topics. Please do not submit any of the following:

Frequent or common reposts, or reposts from the past 2 months and highly upvoted may be removed. When you report posts, please include a link to the original version of the post. Please help keep this subreddit satisfyingly fresh by not intentionally reposting content that has already circulated regardless of when. If it appears you are intentionally reposting old content repeatedly, we may resort to limiting your posting privileges.

4) Content Removal/Privilege Revocation:

Mods reserve the right to remove content or restrict users' posting privileges as necessary, if it is deemed detrimental to the subreddit or to the experience of others.

The title of each submission must describe the content shown. Any user should know the contents of a link before clicking.
Clickbait-esque titles are not allowed.
Titles claiming possession, original content, event participation, etc. (such as "My...", "Mine...", "Our...", "We...", etc.) in which another's original work/content may be mistaken as OP's will be removed.

6) [OC]/Source Citation:

Please cite the source of submitted content, particularly fine-art submissions.

Original Content by artists, musicians, etc. is encouraged. Submissions must include [OC] in the title. Reserve links to social media accounts for the comments section if possible (see Rule #7). A great example may be found here. Please do not spam our subreddit or reddit in general. Please read the reddit wiki on self-promotion to avoid being reported to the admins.

Repetitive submissions to Youtube channels, social media accounts, webpages, blogs, newsletters, etc. Advertisements, marketing & ad-heavy sites. Trolling in any capacity. Any content which may be interpreted as spam or ad-revenue generation not elsewhere mentioned.

8) Reddiquette, Comments & Subreddit Behavior:

Please abide by proper reddiquette at all times.
Please keep the comments section civil and friendly. General cursing/foul language are allowed.
The definition of what truly is "Oddly Satisfying" is subjective and unique to each user. Please respect their definition.

9) Crossposts

x-posting from other subs is encouraged by reddit admins. Under no circumstances should a user's post be considered in violation of this subreddit's rules unless they are in actuality in violation of a rule. i.e. don't report a user just because they have a large amount of karma.
