Demos

A Vivino-style app for cigars: look up any cigar by brand, line or vitola, or identify one from a photo of its band. Rate what you smoke, keep track of your humidor and find shops.

A retro arcade platform game in the browser: shoot enemies small, then grab them before they grow back. Play with up to four players on one keyboard, or create an online room and share the code.

A retro browser game for one to four teddies: search the house, pack four secrets into the case and get out first, while rigging furniture and doors for everybody else. Play against bots or create an online room and share the code.

Calm, safe car lending in Switzerland: renters search electric cars by date, place and make, while owners lend out their own. A single-page app demo; no real bookings are made.

Discover beers and breweries, rate them with half stars and keep your bottles in the Keller. Scan a label to identify a beer and find shops that stock your favourites.

Waze-style navigation for your phone and the Tesla in-car browser: plan a route on the map, send the destination to your car and share road reports with the Klarspur community. Guests can preview it; navigation needs a free account.

Create a custom licence plate image for the Tesla Paint Shop: pick one of 50 European countries, type your number and get a PNG ready for the USB stick. Free and no account needed; not a real, official plate.
