About Rocket Launcher

Rocket Launcher was started by Marcel Panse and Sander Nagtegaal, as the holding company for their brand Unless. There is now a small, but highly effective team. Read more about the company, or check out the history of the product.

About this website and the service

This website is built with Astro and deployed as static files to S3. The underlying UNLESS service is based on a serverless architecture using S3, Cloudfront, Amazon API Gateway, Lambda functions, DynamoDb, Firehose, Redshift and Bedrock. These are all services offered by Amazon Web Services. Besides that, it uses several AI models offered by vendors like AWS, Microsoft, and Google - in a very decoupled way so that your data stays safe.

About our jumbotron pattern

An aperiodic monotile, commonly known as an ‘einstein,’ is a shape capable of tiling the plane exclusively in a non-periodic manner. Our jumbotron pattern features the first true aperiodic monotile: a shape that naturally enforces aperiodicity through its own geometry, without the need for additional constraints such as matching conditions.

The pattern incorporates a polykite, referred to as ‘hats,’ developed through multiple rounds of substitution. This work is based on the scientific contributions of David Smith, Joseph Samuel Myers, Craig S. Kaplan, and Chaim Goodman-Strauss.
