The Speculative Sea Level Explorer App runs on OSX, Windows and Linux. You can download a zip-file which contains the plattform specific application e.g. "application.macosx.zip". Source code and the zip files are available on github.com/b-g/Speculative-Sea-Level-Explorer
Inside the github repository there is a SRTM-file for central europe, see "data/w020n90.Bathymetry.srtm". Run the app and press the "Load SRTM File" button to load the SRTM-file to get started. You can download other SRTM tiles for the rest of the world at the website of the Scripps Institution Of Oceanography. Please note, the SRTM files around the Antarctic currently don't work correctly.
