Drawing with rays!

I've been playing around with the explosion "rays" algorithm in vanilla 1.9 to generate some patterns with explosions.
I don't really know what the use of this is but I think it's quite cool anyway.

When a single block of TNT explodes, it actually shoots out lines rather than just a circle. With REALLY large explosions (using the summon command) you can make these lines easily visible and they can be used to make patterns because of how the equation works. You can also direct the lines using a bedrock tube.

The lines appear because explosions can go between diagonally adjacent blocks (as they don't mathematically touch). However they are weakened so only the rays can pass through.

Check out some patterns I made! http://imgur.com/a/ED5ru

The command to make the large fireball is: /summon Fireball ~ ~ ~ {ExplosionPower:150,direction:[0.0,0.0,0.0]}
You'll want to put the bedrock tube (for directing the brush) quite high in the air for the best affect, and please post any nice patterns you make in the comments using imgur or gyazo so we can all see them. :)
