XMB Wave

     Here is a XMB wave video that I edited from the original to look a bit better (imo) and also to higher the resolution (1080). It might be used for video backgrounds or something, I just thought I'd leave it here.

Here is the original to which I edited:


Differences:
1) This is the Blue XMB only.
2) The blue is more subtle than the one from the original video.
3) Made the sparkles smaller.
4) Wave is sharper.
5) Banding is corrected.

Thoughts about original video:
1) The video is a lower resolution then I would have liked.
2) The banding was pretty bad.
3) The video is not truly seamless but instead it kind of looks seamless (actually an overlay where 2 wave states are similar).
4) Bit rate was too low hindering the overall quality of the video (to be expected due to it being used for Dreamscene so I guess it's understandable).

Project Euler Problems

     The same friend of a friend that got me motivated to make the SudokuGen also showed me this website with these challenge problems and since I have nothing to do these days and am bored anyways, I thought I'd start solving them.


SudokuGen

     One of my friend's friend (I just met him recently) shared some code with me which turned out to be a Sudoku puzzle generator in Java. I don't really know or like Java but it gave me motivation to try my hand at making my own. My algorithm is different from his and I don't really know much about Sudoku generation but enough trial and error and my method works pretty well now. The one big difference from what his has and mine doesn't is backtracking, mine just retries from scratch if it hits a dead end. After improving my algorithm a bit I then went to tackle adding backtracking but that was giving me more of a headache then it should've so I just gave up lol. After this one I have learned a bit and I might plan on making another one using a slightly different algorithm but it should allow me to implement backtracking easier.

As always leave any feedback or suggestions in the comments

UPDATE:
Got around to commenting my SudokuGen code (VB.Net) and modified a couple things as well:

OLD:
Finally here is the source to my Sudoku puzzle generator (VB.Net/Java), on my computer it generates 1000 Puzzles in about 45 seconds, it is by no means fast but fast enough for practical purposes I imagine.

Here are 1000 Sudoku solution outputs :
