Ponticulus Design is a product design and start up company based in Cambridge, UK.

We designed The Mathematical Bridge Model kit in 2016 and have been selling it ever since in and around Cambridge City centre. Ponticulus Design is the creator of The Mathematical Bridge model kit, a high end tourist souvenir and engineering model kit sold in and around Cambridge City. The model of the Mathematical Bridge took around 2 years to design for production. It contains 81 pieces fixed to

a single frame which are then cut out by the builder to be slotted together and glued to fix in place. All pieces are injection moulded using ABS plastic (as with keyboards and mice) with a high tolerance to ensure a tight fit on all parts. The other benefits of using this material are its abilities to adhere to paints and glues and its durability and strength. The bridge can be purchased in white or black, with white being the better option for enthusiasts who wish to paint it with a realistic finish. Ease of assembly was paramount to the design of the final product and it is recommended for ages 14+, however, it is a great project to complete with children of all ages under adult supervision. The project can be completed in roughly 8 hours and to help you along the product comes with a detailed instruction manual. Designed as an ornamental model, educational tool or an activity for a rainy day, the bridge is ideal for model enthusiasts, budding engineers, teachers, and parents who want to introduce their children to STEM (Science, Technology, Engineering and Mathematics)The project gives a satisfying end goal for the builder and the finished model gives a great sense of accomplishment.

Whightwick Manor have finished their rebuild of The Mathematical Bridge... Be sure to check it out if you're ever around Wolverhampton!

15/01/2025

Do you know of Wightwick Manor?

It was a working house owned by the Mander Family, who made their fortune selling paints and varnishes over hundreds of years Globally and were at the forefront in the industry.

Many of the Family were Cambridge Students, Charles Mander studying at Trinity College.

In Cambridge style, they were quite eccentric, and as a result the house is now run by the National Trust to showcase the extensive collection of William Morris work.

But, here's the amazing thing; they had a Mathematical Bridge built in their garden!

The Bridge has recently been renovated and is now open once again for people to see, so if you're ever around in Wolverhampton, I suggest popping in!
