Perseverence Logo

February 19, 2021 by Chris Johnson. Filed under public, twoville.

NASA landed a rover on Mars this week. When I saw the logo for Perseverence, I felt an irresistible urge to recreate it in Twoville. And so I did:

  

    // Circle
with circle()
  center = [50, 50]
  radius = 50
  color = [208, 58, 43] / 255.0

// Star
with path()
  color = :white
  closed = true
  go().position = [-10, 0]
  with cubic()
    position = [0, -10]
    control1 = [-1, -1]
    control2 = [-1, -1]
  with mirror()
    axis = :up
    pivot = :zero2
  with mirror()
    axis = :right
    pivot = :zero2
  with translate()
    offset = [64.81, 75.89]
    
// Rover
with ungon()
  color = :white
  formula = :absolute
  rounding = 5
  size = 15
  xs = [20, ~ + size, ~ + size, ~ + size, ~ + size]
  ys = [25, ~ + size, ~ + size, ~ + size]
  vertex().position = [xs[1], ys[3]]
  vertex().position = [xs[2], ys[3]]
  vertex().position = [xs[2], ys[2]]
  vertex().position = [xs[3], ys[2]]
  vertex().position = [xs[3], ys[1]]
  vertex().position = [xs[4], ys[1]]
  vertex().position = [xs[4], ys[0]]
  vertex().position = [xs[3], ys[0]]
  vertex().position = [xs[3], ys[1]]
  vertex().position = [xs[1], ys[1]]
  vertex().position = [xs[1], ys[0]]
  vertex().position = [xs[0], ys[0]]
  vertex().position = [xs[0], ys[1]]
  vertex().position = [xs[1], ys[1]]

It’s not an exact match. NASA’s landings are better than my own.
