Produced at the Gerrit Rietveld Academie for Frido Troost's class, 2009. Indian ink on cotton, 2.5 x 1.5m. The limits of the alphabet, and the unlimits of numbers: this is a failed attempt at Pascal's triangle, using (and running out of) letters. **Z** marks the end of the alphabet and the _zeroth_ border of the triangle, **X** marks the inside of the triangle within **Z** and beyond **Z**, and **Y** marks the outside of the triangle beyond **Z**. The triangle bottoms out at an arbitrary point. ![[lingua obsidian size.png|680]]
