[5] Landau is a multi-disciplinary artist whose work includes drawing, sculpture, video and performance art, sometimes self-standing and sometimes forming whole environments.

Using salt, sugar, paper and ready-made objects, Landau creates large-scale in site installations, which totally change the spaces she works in.

In one, she inhabited a homeless shelter; in the other Landau created a castaway group show on the water breakers in front of Bugrashov beach.

The following year, she won the first Times/ArtAngel Open commission: to transformed a concrete mixer into a music box, she had every intention of "living in it forever and traveling with the story performed with it in the streets…".

In her 2001 New York City Exhibition, Sigalit turned the Thread Waxing space into a cotton candy crater, spinning the sweet fibers around herself and the audience, to the music of "Arab-Snow".

[13] Returning to Israel during the outburst of the Second Intifada, she worked with Haaretz newspaper front pages, transforming them each day into sculptures of fruit.

[17] In "The Dining Hall" (2007) at Kunst-Werke Institute for Contemporary Art in Berlin, (Germany), She made a chain of installations dealing with private, communal, and public food, feeding and starving.
