+- `ruleset::Ruleset`: the ruleset to run in the interface simulations.
+- `tspan::AbstractRange`: timespan for the simulation
 - `fps::Real`: frames per second to display the simulation
-- `store::Bool`: whether ot store the simulation frames for later use
-- `processor::GridProcessor
-- `minval::Number`: minimum value to display in the simulation
-- `maxval::Number`: maximum value to display in the simulation
+- `store::Bool`: whether ot store the simulation frames for later use.
+- `imagegen::ImageGenerator`: Converts the grid to an image, auto-detected by default.
+- `minval::Number`: minimum value to display from a grid, `0` by default.
+- `maxval::Number`: maximum value to display from a grid, `1` by default.
