Have you ever wondered what a knot looks like rotated 40° or maybe 90°? Or maybe you want to see what a Trilene knot or Constrictor knot looks like from the back? Use your finger to spin the knot and see how it looks from any angle in 3D!

Choose from 101 different knots and see how they’re tied in incredible detail. Watch the knot draw itself or use your finger to tie and untie the knot. Its easy to see where the virtual rope goes in and out and around. (Something about a rabbit and a hole and a tree right? ) Zoom in on the knot to get a closer look or flip it around for another perspective. Can your old school knot app do that?!

KNOTS 3D REVIEWS
———————-
Superb in every way – 5 Stars!
I’m a fairly handy guy (surgeon) and rely on several knots in my practice. Nevertheless I’m pretty hopeless at learning new knots and remembering them, even though I’m a sailor and do some fishing. Knots 3D is the answer. I love every aspect of the app.

Great App – 5 Stars!
I really like this app, I have 4 knot apps, and I use this one the most. As a firefighter rope skills is a must and this app helps keep me “knot prepared”. The zoom and step through the knot using a finger gestures is real handy. The author updates this app with new knots often. I recommend this app.

Vlinders van Nederland

Deze digitale gids Vlinders van Nederland maakt deel uit van een serie mobiele informatiesystemen voor het herkennen van soorten in de natuur. Ze zijn ontwikkeld in het kader van het EU KeyToNature project dat beoogt flora- en fauna-informatie snel en makkelijk toegankelijk te maken.

Deze e-guide bevat een determinatiesleutel, alfabetische soortenlijst, indeling op familie en op kleur van 69 soorten dagvlinders die in Nederland voorkomen. Per soort zijn opgenomen: tekeningen van mannetje en vrouwtje, verspreiding in Nederland (kaart) en Europa (tekst), maanden waarin de soort vliegt, waardplanten en look-a-likes. Deze applicatie is een aangepaste heruitgave van de CD-ROM Dagvlinders van Europa, gepubliceerd door ETI in samenwerking met de Vlinderstichting (ISBN 90-75000-86-3).

De geïllustreerde determinatiesleutel is gebaseerd op Butterflies of Europe door T. Lafranchis (2004). Door uit één of meerdere opties te kiezen kan een soort snel op naam gebracht worden. Behalve Vlinders van Nederland is er een e-flora, een paddenstoelengids  en een serie e-fauna’s (vogels, vissen, zoogdieren, reptielen en amfibieën). Andere titels zijn in voorbereiding (de Libellen van Nederland verschijnt in augustus 2013).
