Link to which Gyroscope you mean? It's a very general search term and I haven't come across a service named that otherwise.
In any case, I doubt so, or it doesn't even matter. Nothing in the world is really so unique, and especially app ideas on the internet. It's not a new idea to make an infographic style poster from data, so who's ripping off whom?
Googling for gyroscope poster or gyroscope github doesn't produce anything relevant in the first few results. I would suggest "rip off" is too strong a word, especially when the thing it's supposed to be ripping off is apparently not well known and therefore possibly unknown to the creator of this tool.
I too tried to do some searching for "gyroscope" after you called my little app a "blatant rip off". I found absolutely nothing, so thanks to others for adding some links.
