# The Ninth Day of Tiny Code Christmas Extra

# Tiny Code Christmas - Day 9 - EXTRA⌗

Welcome to Day 9 of Tiny Code Christmas EXTRA! We’re glad that you’re joining us again on this festive journey into the world of sizecoding. TCC Extra is intended for people who completed Tiny Code Christmas last year and want a new challenge!

If you haven’t already, read the overview to find out what Tiny Code Christmas is all about!

## The Challenge: 3D Dot Landscape!⌗

The **first challenge** is to explore the effect and the various parameters. The **second challenge** is to create the tiniest implementation possible while retaining the properties of the original: dot grid, plasma height map, 3d persepective.

Both the TIC-80 and PICO-8 code are below as a starting point or you can write your own from scratch, no requirement to use these.

## TIC-80⌗

```
t=0
function TIC()
t=.02+t
cls(0)
for x=-120,120,3 do
for z=0,1000,8 do
y=(math.sin(math.sin(t/2)+x/50)*3+math.sin(z/50-t))*3
pix(120+x/(z*1.8-1200)*1200,(y-40)/(z*1.8-1200)*1200,y/1.8)
end
end
end
```

## PICO-8⌗

```
t=0
r=0.159 --rads to turns
function _draw()
t=.02+t
cls(0)
for x=-120,120,4 do
for z=0,800,12 do
y=(sin((sin((t)*r)+x/50)*r)*3+sin((z/50-t)*r))*3
pset(120+x/(z*1.8-1200)*1200,(y-40)/(z*1.8-1200)*1200,y)
end
end
end
```
