my hommus recipe
USE HOME-COOKED CHICKPEAS AS BASE. NOT THE STUFF FROM CANS.
cook chickpeas without anything. they freeze well, so make as much as you want. cook them SOFT.
roughly:
* 1 cup of chickpeas
* 2-3 spoons of tahin
* 2-3 spoons of olive oil
* 2-4 spoons of lemon juice (to taste, I like with more)
/*
Generates a trail that is always facing upwards using the scriptable mesh interface.
vertex colors and uv's are generated similar to the builtin Trail Renderer.
To use it
1. create an empty game object
2. attach this script and a MeshRenderer
3. Then assign a particle material to the mesh renderer

Create dynamic equirectangular maps for Unity. These have the benefit that, as they're flat images, you can sample lower mips to get blurry reflections. The straight cubemap version (detailed here: http://www.farfarer.com/blog/2011/07/25/dynamic-ambient-lighting-in-unity/ ) will give you hard seams when you sample mips from the cubemap. Although…
