Creative studies
Here are some design & creativity studies produced from demo sites, archived landing-pages and projects that never made it past the development phase.
NairaEx~ 15 hours
Landing-page for debit-cardApprox. 15 of development hours View demo
- custom graphics
- Layout
- keyframe animation loop
NairaEx is a Nigerian company providing bitcoin services to the African and Canadian markets.
This landing page was for a crypto debit-card, to be used in Canada.
The design features colours associated with the Nigerian flag, and offers light-weight, pure-CSS animation for the debit-card graphic.
BTCPay Server~ 15 hours
Landing-page / Experimental homepageApprox. 15 of development hours View demo
- custom graphics
- Layout
- UI
Flat18 has played an important part in the development of the BTCPay Server website.
In its early days, we tried many iterations of the website, using design to strike the right balance of seriousness and credibility while remaining inviting and approachable.
This is one of many rejected samples provided. It features an experimental hero element with an embedded .gif element, experimental carousel for displaying the product features, and some whimsical graphics and page elements.
Zismo.io~ 100 hours
P2P Trading platform prototypeApprox. 100 of development hours View demo
- custom graphics
- Layout
- UI
- UX
- databases
- encryption
- geolocation
This peer-to-peer trading platform was designed to work similarly to local bitcoins, but with huge improvements to the user experience.
The development of this platform led to the creation of some unique UI elements; like the 'vertical cover-flow' element for listing trades.
Logo & Icon Design~ 2 hours
Icon designApprox. 2 hrs per design
- multiple logo iterations
- monoscrome and coloured specimen
- product mockups
Logos are a design introduction for any project, and can set the tone for the UX and interface design ass a whole.
We enjoy designing logos that are vibrant, simple and meaningful to the product it represents.
Incognet~ 10 hours
Website redesign proposalApprox. 10 of development hours View demo
- custom graphics
- Layout
- JavaScript-avoidance
- UI
- backend whois middleware
One main objective in this re-design proposal, is the de-cluttering of the site's existing content.
However, it was also important that the site felt like the design choices were 'considered' and deliberately understated.
Copious padding and judicious use of graphics hidden in menu dropdowns, make the UI feel stylish and characterful without compromising the minimalistic, clean look.
