+
+### Bugs
+
+1. **Compile time Error**
+
+    Line 97: Syntax error vec2 (not vec)
+
+    Compile time error that was present from the beginning. Easy to spot, Shadertoy indicates such errors and will not run untill they are solved.
+
+2. **Aspect Ratio**
+
+    Line 11: Correct the aspect ratio (iResolution.x / iResolution.y)
+
+    The spheres were not uniform and stretched along the x direction. Since the UV calculation looked right, we looked at the ray cast code and found that the aspect ratio was being calculated incorrectly.
+
+3. **Incorrect Argument**
+
+    Line 100: Pass in the correct UVs (uv2)
+
+    The image was centered at the lower left corner, so we suspected something with the UVs was still incorrect. This one took me a while and I went back to verify the ray cast code (even pulled up Adam's raycasting slides :P). Finally Megan found out that the uvs being input to the raycast funtion were incorrect.
+
+4. **Raycast Distance**
+
+    Line 18: Increase the max distance for ray marching (was 64, changed to 300)
+
+    The edges of the ground near where they met the spheres were warped and those artifacts were similar to what we've seen in the class.
+
+5. **Ray Direction**
+
+    Line 75: Fixed ray calculation for specular reflection
+
+    The sphere reflection looked off and that made us look into the code handling reflection. I had to look up the parameters for the reflect function that made it clear that the 1st expected input parameter is ray direction and not ray origin
