No.878 by Torsten Linß – Interesting twins with a change of exotic fairy pieces. (JV)
Definitions:
Princess(PR): Combines Bishop and Knight (B + S).
Empress(Em): Combines Rook and Knight (R + S).
Helix Knight: Similar to the Nightrider, but the 1:2 jumps are not on a straight line, but on a helix around an orthogonal line. Example: Helix Knight al moves a1-b3-a5-b7 or a1-c2-a3-c4-a5-c6-a7-c8, checks the enemy King on c8, if the relay squares are empty, and checks the enemy King on a5 simultaneously on different routes (thus multiple pins are possible).
Diagonal Helix Knight(DS=Diagonalspiralspringer): spirals around diagonals instead of vertical/horizontal lines.

Outstanding and kind of unbelievable. Obviously silicon, but outstanding and kind of unbelievable nevertheless.
Torsten’s “Silicon Rose” had to wait for over an year for a comment!
I too seem to have missed seeing it at that time…
As Juraj said – unbelievable is the word: 3 edge of the board model mates from the solitary black rider. With great unity:
1. Twinning method
2. Final quiet moves by WK
3. The mates are by a pinned rider capturing its pinner
