Rules -- Proof of Quilt

Proof of Quilt was invented by the Japanese puzzle company Nikoli (under the name Shakashaka) in 2008. 
1. Place black isosceles right triangles in some of the white cells in the grid. Each triangle must occupy exactly half of its cell, but may be in one of four orientations (◢, ◣, ◤, or ◥). A white cell may only contain one triangle.
2. Every contiguous region of white must be shaped like a rectangle (or a square).
3. A number in a black cell represents how many triangles share an edge with that cell.

Monday Mutant 58: Blackbarrier Jam / Streaming Content (cipher)

In the Blackbarrier Jam puzzle on the left and in the Streaming Content puzzle on the right, the given numbers have been replaced by letters; all instances of a particular letter represent the same number, but two different letters must represent different numbers. (This applies whether the letters are in the same grid or not.) The rules are otherwise unchanged.
My most sincere apologies for today's Monday Mutant being late; I was debating whether to put the series on hold for the holidays, but decided against it a few hours ago.

Puzzle 475: Fencing Match 45

Merry Christmas! (Well, in the Central time zone, at least. Those of you living west of that time zone still think it's Christmas Eve.)

On this holiday, Christians commemorate the birth of Jesus Christ, who has been alternately portrayed as a generous feeder of the hungry and as kind of a jerk towards tall people. It is also a day when some Christians complain about how secular the holiday has become with its focus on materialism and Santa Claus rather than on Jesus, and demand that the "Christ" be put back in "Christmas". This large puzzle not only puts the "Christ" in "Christmas", but the "mas" as well, or more technically the "más" (the Spanish word for more). Oh, and for those non-Christians out there who are offended to see crosses in a logic puzzle, think of it this way: Christmas is about the birth of Christ, but crosses represent the death of Christ! As such, I'm really offending Christians just as much, if not more.

That paragraph aside, I hope you enjoy this Christmas present from me to logic puzzle fans everywhere.

Puzzle 474: Circumnavi-Gates 17

Fans of Chip's Challenge or of my puzzles will be excited to know that these two things have come together in what is known as Chip's Challenge Level Pack 3! From what I understand, this official sequel to Chip's Challenge Level Pack 2, which is in turn an unofficial sequel to the original 149 levels of Chip's Challenge, contains two levels that I created (levels 43 and 98) and 147 levels that other Chip's Challenge fans made. I am truly glad to have been a part of this.

Four-Puzzle Derby minor update!

I suspect that all of my readers have been waiting with bated breath to see what kind of booby prize I decided to offer in the Four-Puzzle Derby. Having received confirmation of the booby prize's arrival in the appropriate recipient's mailbox, I will now reveal what it was to the whole world!

Warning: the following results contain spoilers (obviously)! If you wish to solve the contest puzzles yourself, please do so before reading on!

Monday Mutant 56: Polyominous (skyscrapers)

In this Polyominous puzzle, a number to the left or right of a row or above or below a column represents how many numbers in that row or column can be seen from that direction. A number is visible if and only if it is strictly greater than any other numbers in the row or column between that number and the edge (and is blocked from being seen if a number greater than or equal to it is in the way). The rules are otherwise unchanged.
This puzzle borrows some elements from Skyscrapers, probably one of the more well-known logic puzzle genres to have no real links to Japan. Normally, Skyscrapers doesn't involve polyominoes, but does involve a Latin square.

Puzzle 464: Process of Illumination 35

I would like to promote three things whose only commonality is my involvement in each.
1. Four Puzzle Derby! It's a contest where you can win puzzle books imported from Japan! The deadline is less than a week away, so hurry up and enter.
2. Mega Micromusic! This awesome release by Dual Mode Records contains 8 songs created using the Record MakerMatic in WarioWare DIY, which can be basically described as a new generation of Mario Paint with much more interactivity. Track 3, the surreally titled "2120 Census", was composed by me.
3. 30s30d: A Month's Worth of Composing! While I didn't advertise it on my blog (until now), I spent the entire month of November writing one new song every day. Song 14, "Link and the King Get Logical", uses sound effects from the logic puzzle games by Everett Kaser, which some readers of this blog might recognize. There are also 10 WarioWare DIY tunes and 19 NES chiptunes.
Now that I've promoted those three things, solve this not-very-difficult puzzle.

Monday Mutant 55: Polyominous (cipher)

In this Polyominous puzzle, the given numbers have been replaced by letters; all instances of a particular letter represent the same number, but two different letters must represent different numbers. The rules are otherwise unchanged.
This puzzle is a tribute to one of my favorite Christmas movies (er, THE WINTER SOLSTICE movies) of recent time.
