The beads on this oversized abacus designed by Ontario-based Jeff Goodman Studio are made from colourful pieces of blown glass.
The Devil's Abacus screen was created by the glassblowing studio as a large-scale version of the ancient counting tool.
Set within a wooden frame, vertical rods hold multiple glass beads that can be adjusted up and down, creating a customisable partition.
Its coloured glass elements were designed to complement the gems of the jewellery pieces for sale in the shop.
"We envisioned our new abacus modular screen as a tailored piece of architectural jewellery inside the store," said Jeff Goodman Studio creative director Sylvia Lee, "but given its 7.5-foot (2.3-metre) height, it's a dramatic counterpoint to the store's beautiful but small products."
The window installation gave one example of how the screen could be displayed. The studio envisages the screen to be used to divide residential or commercial spaces, and can produce bespoke versions on request.
"The abacus is available in any colour of glass, with varying shapes, in a shiny or matte finish," said Lee.
Coloured and stained glass appears to be continuing its moment in vogue, after it was noticeably prevalent during Milan design week last year.
TODO took place across the city from 16 to 22 January 2017, coinciding with the Interior Design Show at the Metro Toronto Convention Centre.
