Hey,
I’m working on launching a new website for a indie games development team that I am trying to set up.
That aside, I am trying to source images for all the open source technologies that we use so it can be referenced on the website. I’ve noticed that the logo for MonoGame has changed recently and I was wondering if there was a higher-res version of the one that is being used on the home page of MonoGame.net at all?
Thanks in advance 
You can find the logos here:
As for this one:
MonoGame
An open-source, reverse-engineered version of the XNA game framework.
By no means is MonoGame reverse-engineered. That would involve stealing code from Microsoft. Such practices are strictly forbidden.
“Reverse engineering is the process of creating a similar device, object, or system after examining the original and discovering its technological principles through analysis of its structure, function, and operation.”
I would argue that MonoGame utilizes the same structure as the XNA framework and operates with a different rendering API behind all the XNA framework based classes.
To continue your quote from Wikipedia:
The process often involves disassembling something (a mechanical device, electronic component,
computer program, or biological, chemical, or organic matter) and
analyzing its components and workings in detail, just to re-create it.
Calling MonoGame a reverse-engineered XNA makes people feel that it’s based on the disassembling of XNA and hides the tremendous amount of work that was put into it in order to avoid the usage of disassembly.
That’s a bold claim to make on behalf of everyone. 
I do not think for a single second that MonoGame’s underlying functionality was based on disassembled code.
“reverse-engineered” can have some negative connotations. I recommend sticking closer to how the MonoGame team describes the project:
MonoGame is an Open Source implementation of the Microsoft XNA 4 Framework.
