Welcome to part 3 of Quark's quest to make an image puzzle that isn't solved in under an hour. Like the last one, this will be much more difficult than the last.
In the below encrypted message, there are stages that lead from one to the next. There are two main words to discover, one at the ~75% completion mark, and one at the finish line. Put them together and you'll have a phrase related to computing.
What is that phrase?
Hints definitely aren't needed to solve this but if it goes past a day or two I'll start giving hints. However, if this is solved under two hours then I'll admit that I underestimate this puzzling community and I'll be forced use drastic measures for part 4.
Note: The "ovals" in the picture are different sizes, ignore this because I made this sloppily in Paint. This was originally supposed to make smart puzzlers go "well he probably doesn't want us measuring their radii/center position so I'll ignore it" but I realize it's better to explicitly state it.
Note 2: There is no extra information in this puzzle other than the size thing mentioned above. I realized there is a phrase related to computing that is discovered around the 40% completion mark but this is not related to the answer and is just a hint on how to progress further.
