Feel free to use our logo to publicise the WaLSA-related activities. The following file formats are provided for various purposes. The PDF, EPS, and SVG files are vector images designed for use at any size (the preferred formats). The PNG files are smaller in size and are good options for digital use (e.g., presentations or web). All files are transparent, thus, depending on dark or light backgrounds, either white or black versions of the logo may be used.
