That's the solution for the DiamondPrint problem: http://exercism.io/exercises/kotlin/diamond/readme
class DiamondPrinter {
fun printToList(char: Char): List<String> {
val size = ('A'..char).count() * 2 - 1
val half = size / 2
return (0..half).map { lineIndex ->
StringBuilder("".padStart(size))
.apply {
setCharAt(half + lineIndex, 'A' + lineIndex)
setCharAt(half - lineIndex, 'A' + lineIndex)

#!/usr/bin/env python
import os
for filename in os.listdir('.'):
if filename.endswith(".webm") or filename.endswith(".mp4"):
os.system('ffmpeg -i %s -r 10 -vf scale=480:-1 %s.gif' % (filename, filename))
continue
