'''''Thinking with Time Machine''''' is a 2014 [[Video game modification|modification]] for ''[[Portal 2]]'' developed by Ruslan "Stridemann" Rybka, and released by SignHead Studio. The game revolves around the concept of a tablet-like [[time machine]] that is controlled by the player. The tablet allows the player to record their movement and replay the recordings, creating a double that performs the recored tasks. Additionally, the mod allows the player to see their own legs by looking down.
Initially released on the ModDB[[Mod DB]] website, ''Thinking with Time Machine'' went through the [[Steam Greenlight]] process, after which it was released as a free modification on [[Steam (service)|Steam]] on April 18, 2014. The time machine concept and the ability for the player to see their own legs by looking down were commended by critics, while the lack of usage of the [[portal gun]] and the mod's short length were criticized.
