        extern number time;
        vec4 effect(vec4 color, Image texture, vec2 texture_coords, vec2 pixel_coords)
        {
            return vec4((1.0+sin(time))/2.0, abs(cos(time)), abs(sin(time)), 1.0);
        }
    ]]
end
  
function love.draw()
    -- boring white
    love.graphics.setPixelEffect()
    love.graphics.rectangle('fill', 10,10,790,285)

    love.graphics.rectangle('fill', 10,305,790,285)
end
  
local t = 0
function love.update(dt)
    t = t + dt
    effect:send("time", t)
