Portrait Painting Lesson -- Light, Shadow, and Soul

I'll teach you to paint a face that looks like a person, not a photograph. We work in oil on canvas, natural light from one window. The secret isn't technique -- it's empathy. You have to love the face you're painting, even the ugly ones. Especially the ugly ones.

Plein Air Painting Kit -- Portable Easel + Supplies

French box easel, oil paints (18 colors including chrome yellow -- my obsession), brushes, turpentine, linseed oil, and 6 pre-stretched canvases. Everything you need to paint outdoors the way the Impressionists did. Go to a wheat field. Set up. Paint what you feel, not what you see.

Expressive Painting Workshop -- Color as Emotion

I don't teach technique. I teach seeing. We go outside, we look at the sky, and I show you that it's not blue -- it's cobalt and ultramarine and violet and green, swirling. The color is the feeling. The brushstroke is the heartbeat. If your painting looks like a photograph, you're not painting -- you're copying.

Self-Portrait Workshop -- Painting Your Truth

Forget flattering yourself. Paint what's real. The scars, the joy, the fury, the love. We work in oil or acrylic on small canvases. I'll teach you about color symbolism from Mexican folk art -- what red means, what blue means, why I put monkeys and parrots in my paintings. Bring a mirror. Bring honesty.

Mexican Folk Art Supplies -- Retablo Painting Kit

Small tin sheets, oil paints, fine brushes. Everything for painting retablos -- the small votive paintings I collected and was inspired by. Paint your miracle, your gratitude, your survival. The format is tiny. The feeling is enormous.

Cryptography & Logic Workshop

Learn the fundamentals of code-breaking. Caesar ciphers, substitution ciphers, frequency analysis, and the principles behind Enigma. No math degree required -- just patience and the willingness to think backwards.

Algorithm Design Workshop -- Think Like Ada

Learn to decompose problems into repeatable steps. We start with simple sequences, add loops, add conditionals, and build up to something that could compute Bernoulli numbers -- the algorithm I wrote in 1843. Paper and pencil only. No computers. The machine is not the point. The pattern is the point.

Artist's Anatomy Sketchbook -- Da Vinci Method

A reproduction of my anatomical drawings with blank pages interleaved for your own studies. I dissected 30 corpses to understand how the body works. You can study from the drawings instead. Learn where the muscles attach, how the hand articulates, why the shoulder moves the way it does.

Technical Drawing & Perspective Workshop

I'll teach you linear perspective, isometric projection, and how to draw machines that could actually be built. Bring a ruler, compass, and pencils. We draw by hand. No CAD. If you can't draw it, you don't understand it.

Mathematics Tutoring -- From Zero to Algebra

I gave Europe the number zero. I wrote the book on algebra (al-jabr). I'll teach you both. We start with the Hindu-Arabic numeral system, learn why it's superior to Roman numerals, and work up to solving equations. The algorithm is just a recipe. Follow the steps.

The C Programming Language (K&R, 2nd Edition)

The book I co-wrote with Brian Kernighan. 272 pages. Every C programmer alive has read it. Clear, concise, no padding. The entire language specification fits in your back pocket. Borrow it, read it, write hello world, return it.

Git & Version Control Workshop

I wrote Git in two weeks because I was angry. I'll teach it to you in two hours because you need it. Branching, merging, rebasing, conflict resolution. The fundamentals that 90% of developers still don't understand.
