Nathan, for his 10th birthday, requested a Terraria celestial event cake, with a four-sided pillar, each side of which corresponds to a phase of the celestial event – Nebula, Stardust, Vortex, and Solar – and includes the appropriate monsters.
Fortunately, after Sam’s last Terraria cake, I am expert at painting pixel-y gum paste Terraria characters. The guy on the side is Nathan’s avatar, with a Horseman’s Blade, which he specifically requested.
The tower is cake, mounted on a pipe connected to a bevel gear, so that the cake can be turned with a crank.
I wanted to make the backdrop change color to correspond with the celestial event phase, so I made a light box like the one I made for the Terraria Blood Moon Cake. Inside are strips of LED tape in pink, yellow, blue, and green. When the cake turned, a strip of copper tape on the gear created electrical connections that lit the appropriate color LEDs as each side of the pillar came to the fore. It quite well at home, but the party was outside on a sunny day, so with that much ambient light the color change was virtually imperceptible.
As usual, I made about four times as much cake as the party required.
