+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,

+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,

+
+## How it works
+
+This is a **Silicon Art** project for TinyTapeout using the **custom GDS** workflow. A **pixel pig** artwork and **canary token text** are directly written as metal polygons on the silicon, visible under a microscope when the chip is fabricated.
+
+The design includes:
+1. **Custom GDS** with pixel pig + canary token rendered on metal `.drawing` layers
+2. A decorative border frame around the design
+3. All required TinyTapeout pins properly defined on Metal4.pin layer
+4. Power pins (VPWR, VGND) on TopMetal1.pin layer
+5. A minimal Verilog stub that passes inputs through with an XOR pattern
+
+**Important DRC note:** Art uses `.drawing` layers (datatype 0) which are the only fabricated layers in TinyTapeout's IHP whitelist. All geometry meets DRC requirements:
+- Pixel art: ~7.88 µm pixels (min: 0.20 µm) ✅
+- Text strokes: ~0.19 µm at 3µm font (min: 0.16 µm) ✅
+- Border: 1.0 µm wide (min: 0.16 µm) ✅
+- Density fill: 2µm squares added to reach 35-60% metal coverage ✅
+
+The design fits in the 202.08 × 154.98 µm tile area (TinyTapeout IHP 1x1 tile). Pin positions are precisely calculated to match the TinyTapeout IHP template DEF file.
+
+## How to test
+
+The functional logic is minimal (just for TinyTapeout compatibility):
+
+1. Apply any 8-bit input pattern to `ui_in[7:0]`
+2. The output `uo_out[7:0]` will be the input XOR'd with 0xAA
+
+For example:
+- Input: 0x00 → Output: 0xAA
+- Input: 0xFF → Output: 0x55
+- Input: 0xAA → Output: 0x00
+
+## External hardware
+
+No external hardware required. This is primarily an art project.
+
+**To view the silicon art after fabrication:**
+- Use an optical microscope with at least 50-100x magnification
+- A metallurgical/reflected light microscope works best
+- Look for the pixel pig (left) and canary token text (right)
+- Art is on Metal1.drawing (8/0), Metal2.drawing (10/0), Metal3.drawing (30/0)
+- The patterns appear as bright/reflective metal under the microscope
+- The pig uses 81 pixels (~7.88 µm each), text uses 3µm font
